Abstract ：
The Ag-based superionic argyrodites with liquid-like ultralow lattice thermal conductivity have garnered widespread attention as promising thermoelectric materials. However, the inferior performance of n-type argyrodites does not match the p-type counterpart for device construction. Here, the two new cubic n-type Ag-based argyrodite compounds Ag4M0.5S2Te (M = Sn and Ge) are synthesized. They crystallize in the F (4) over bar 3m space group with excellent structural stability. The unique triangular [AgS2Te](5-), rod-like [AgSTe](3-), and complex cage-like [Te4Ag36](28+) clusters together with the vibrations of weakly bonded Ag+ ions result in large lattice anharmonicity and enhance the scatter of acoustic phonons. These structure characters lead to the ultralow lattice thermal conductivity (kappa(lat)) of 0.30-0.32 W m(-1) K-1 near the amorphous limit 0.24 W m(-1) K-1 at 525-823 K. Moreover, the power factor enhanced from 1.53 mu W cm(-1) K-2 for Ag4Sn0.5S2Te to 2.61 mu W cm(-1) K-2 by introducing Te deficiencies, resulting in a high ZT of 0.74 at 823 K for Ag4Sn0.5S2Te0.92, which is 95 % higher than that of the pristine sample.

Abstract ：
A BiFeO3 crystal has both antiferromagnetism and piezoelectricity at room temperature. Unfortunately, it is difficult to grow a larger-size and high-quality BiFeO3 single crystal. By a top-seeded solution growth method using Bi2O3 as a solvent, centimeter-size Bi1-x Sr x Fe1-y Ti y O3 crystals were successfully grown in this paper. Moreover, the lattice symmetry of the Bi1-x Sr x Fe1-y Ti y O3 crystals changes from rhombohedra to cube with the increase in Sr2+ and Ti4+ doping concentration. The magnetization of a Bi0.6Sr0.4Fe0.6Ti0.4O3 crystal reaches 0.25 emu/g at room temperature, which is about 3.1 times as large as that of a BiFeO3 single crystal, in an applied magnetic field of 10,000 Oe. The piezoelectric effect is observed on all Bi0.8Sr0.2Fe0.8Ti0.2O3-2 wafers; especially, strong response was observed on the < 111 >-oriented wafer. By optimizing the type and the concentration of doped ions, it is expected to obtain large-size doped BiFeO3 single crystals with better magnetic and piezoelectric properties.

Abstract ：
Objective Magneto-optical crystals are pivotal components that determine the performance of magneto-optical devices. Through the hybridization between the excited Bi3+ 6p orbital and Fe3+ 3d orbital, the modification of superexchange induces a strong mixing between crystal field states of varying energies, greatly enhancing the magneto-optic effect in ferrite. Doping Bi3+ ions emerges as a key approach to enhancing the magneto-optical properties of commercial Y3Fe5O12 (YIG) crystals. However, despite being the only known room temperature single-phase multiferroic material, there is scarce literature reporting on the magneto-optical properties and its applications in magneto-optical devices of the perovskite BiFeO3 with a high concentration of Bi3+ . This can be attributed to its unique spiral G-type antiferromagnetic structure, which exhibits weak macroscopic magnetism. Additionally, due to its trigonal crystal system and birefringence effect, BiFeO3 demonstrates a considerably feeble magneto-optical effects. In the present study, stable pure phase cubic BiFeO3 single crystals are grown by doping Sr2+ and Ti4+ ions. This eliminates the birefringence effect of the trigonal BiFeO3 and induces strong magnetic and magneto-optical effects, providing a useful reference for exploring high-quality, large-size new magneto-optical crystals suitable for high-performance magneto-optical devices. Methods Bi2O3 is chosen as the self-flux solvent, and a series of crystals including Bi1-xSrxFeO3 and Bi1-xSrxFe1-xTixO3 (x=0‒0.5) are grown by using the molten salt method. The crystal structure and lattice parameters of Sr∶BiFeO3 and Sr/Ti∶BiFeO3 are determined by XRD spectra analysis and Rietveld refinement. The structure and morphology changes of BiFeO3 crystals are observed by scanning electron microscopy (SEM). Elemental valence states in the crystals are analyzed using X-ray photoelectron spectroscopy (XPS), while magnetic properties and magneto-optical performance are characterized by a vibrating sample magnetometer and magneto-circular dichroism spectroscopy respectively. Results and Discussions The Rietveld refinement results show that Bi0.7Sr0.3FeO3 and Bi0.7Sr0.3Fe0.7Ti0.3O3 crystals belong to the Pm-3m space group of the cubic crystal system. The cell parameters of Bi0.7Sr0.3FeO3 and Bi0.7Sr0.3Fe0.7Ti0.3O3 crystals are 3.9517 Å and 3.9447 Å, respectively. The SEM images also prove that BiFeO3 changes from a triangular columnar crystal to regular cubic crystals. When the cooling rate of crystal growth is controlled within the range of 1‒10 ℃/h, the size of cubic crystal grains are 20‒50 μm. Sub-millimeter size crystal grains are obtained when the cooling rate of crystal growth is 0.5 ℃/h. However, as the grain size increases, the distance between the stress field of the dislocation packing group and the dislocation source in the crystal also increases, resulting in a stronger stress field and subsequent grain deformation. XPS spectra show that doping of heterovalent elements leads to the production of Fe2+ and high-valence iron. The saturated hysteresis loop and MCD spectra indicate that the magnetic and magneto-optical properties of BiFeO3 crystal can be significantly enhanced by doping of Sr2+ and Ti4+ ions, but the coercivity has not significantly changed. The saturation magnetization of Bi0.7Sr0.3Fe0.7Ti0.3O3 is observed to be 0.31 (A·m2)/kg, which is approximately four times that of BiFeO3, while exhibiting a significant MCD ellipticity value (ψF) of 179 (°)/cm, in contrast to the negligible MCD signal produced by BiFeO3 (Fig. 7 and Fig. 8). This can be attributed to the introduction of Sr2+ and Ti4+ ions, leading to the elimination of the birefringence effect, as well as the suppression of the periodic spiral spin magnetic structure and providing additional electronic transition pathways. Consequently, this enhances both the magnetic and magneto-optical properties of BiFeO3 crystals. Conclusions A series of non-birefringent cubic Bi1-xSrxFeO3 (x=0.3, 0.4, 0.5) and Bi1-xSrxFe1-xTixO3 (x=0.2, 0.3, 0.4, 0.5) crystals are grown by using the molten salt method. The introduction of Sr2+ and Ti4+ ions causes lattice distortion of BiFeO3 and inhibits its periodic helical spin magnetic structure. Especially, when Ti4+ ions are introduced to replace part of Fe3+, the helical G-type antiferromagnetic structure of BiFeO3 will be broken, thereby releasing part of the spin magnetic moment of Fe ions. This results in the magnetism and magneto-optical effects of Sr∶BiFeO3 and Sr/Ti ∶BiFeO3 are significantly stronger than that of BiFeO3. The saturation magnetization of Bi0.7Sr0.3Fe0.7Ti0.3O3 is approximately 4 times that of BiFeO3. Its MCD ψF value is observed to be 179 (°)/cm, which is about 4.5 times that of YIG, a popular commercial magneto-optical material tested under the same conditions. With high saturation magnetization, low coercivity and strong magneto-optical effect, Sr/Ti∶BiFeO3 crystals are expected to be used as core magneto-optical materials in magneto-optical modulation, magneto-optical sensing, magneto-optical imaging and other devices, and are hopefully applied in optical communication, laser display, biomedicine, etc. © 2024 Chinese Optical Society.

Abstract ：
The nickel element doped holmium oxide (Ho2O3:Ni) transparent magneto-optical ceramics were fabricated by vacuum sintering and the dopant impacts on structure features and Faraday effects were investigated. The starting oxide powders were synthesized by pyrolyzing the resulting layered holmium-based hydroxide nanosheets prepared from a chemical precipitation route using the sodium hydroxide as precipitant at the freezing temperature. Upon high-temperature sintering, the Nii center dot center dot${\mathrm{Ni}}_i<^>{ \bullet \bullet }$ defect is introduced by Ni2+ substitution for Ho3+ to form the interstitial solid solution. The 1 at.% Ni2+ doped Ho2O3 ceramic sample exhibits an in-line transmittance of similar to 70.04% at 1 550 nm with a relative density of similar to 99.88%, while more Ni2+ incorporation (e.g., 2-5 at.%) even leads to a completely opaque state. The magneto-optical transparent Ho2O3:1%Ni ceramic developed in this work has Verdet constants of similar to-195, -65, and -29 rad/(T center dot m) at 635, 1 064, and 1 550 nm, respectively, which are similar to 1.8-fold higher than the commercial terbium gallium garnet crystal or similar to 1.4-fold higher than the pure Ho2O3 ceramic. This material also possesses relatively large figure of merit of similar to 14.6 degrees/T at 1 064 nm and relatively high thermal conductivity of similar to 7.5 W/(m center dot K) at room temperature. The magneto-optical transparent Ho2O3:xNi2+ (x = 1-5 at.%) ceramics were fabricated by vacuum sintering using layered rare-earth hydroxides as the precursors. Our results demonstrated that elemental nickel was a quite effective dopant for enhanced Verdet constant and the optimum ceramic composition of Ho2O3:1%Niexhibited good potential to apply to the high-power laser system, especially for use in the near-infrared region. image

Abstract ：
Bi-doped rare earth iron garnet (Bi:RIG) crystal is an ideal magneto-optical material for optical isolators in the near-infrared band, which has been widely used in optical communication applications. In this paper, centimetersized and good-quality Ni2+-doped Bi:RIG crystals were successfully grown by top-seeded solution growth (TSSG). The transmittance reaches 72.6% at 1550 nm, which is higher than commercial Bi:TbIG crystal and close to the theoretical values of RIG crystals. Doping Ni can not only greatly improve the transmittance, magnetic, and magneto-optical properties, but also decrease the Faraday rotation temperature (FTC) and wavelength coefficients (FWC) of the Bi:RIG crystal. The FTC and FWC of (Bi0.37Ho1.18Eu0.83Gd0.62)(Fe4.20Ni0.25Ga0.55)O-12 crystal reduced to - 6.3 x 10(-4) K-1 and 8.0 x 10(-4) nm(-1), which are about 30% and 80% of commercial Bi:TbIG crystal, respectively. (Bi0.37Ho1.18Eu0.83Gd0.62)(Fe4.20Ni0.25Ga0.55)O-12 exhibits potential for utilization in new high -performance, wideband magneto-optical isolators, and is expected to find application in the field of wavelength division multiplexing fiber communication.

Abstract ：
Cubic Sillenite Bi25FeO40 (BFO) could become a new magneto-optical material due to its high concentration of Bi3+ and no birefringence. But its weak magnetism causes the magneto-optical properties to be far from the requirements of practical applications. Doping magnetic Fe3+ and Ni2+ ions to improve the magnetism and magneto-optical properties of BFO (Bi19Ni2.8Fe4.2O40) film on fluorine-doped tin oxide (BNFO/FTO) is discussed in this paper. Another focus of this paper is to discuss the magneto-optical properties modulated by the electric field. The cubic BNFO film has weak piezoelectric effects, which makes it difficult to modulate its magnetooptical effect by electric field. A polarity symmetry induced by the Schottky junction between Au metal layer and BNFO semiconductor layer (Au/BNFO) compensates for cubic symmetry, and the piezoelectric effect can be improved. By applying an electric field, its magnetic circular dichroism (MCD) ellipticity |Psi F| gradually decreases as a direct current voltage from 0 V to 10 V in a magnetic field of 2500 Oe, demonstrating the feasibility of this strategy. These results indicate a new way for highly symmetric magneto-optical materials to modulate magneto-optical effects in electric fields.

Abstract ：
Based on the thermal stability analysis by density functional theory and the crystal phase optimization by tolerance factor, the crystal structure was designed. So, a new cubic Ce3Sc2Ga3O12 (CSGG) garnet material with a high Ce3+ concentration was synthesized. The centimeter-scale CSGG crystal was grown by the Czochralski method. CSGG exhibits fine magneto-optical properties, which are attributed to the stable valence and high concentration of rare-earth Ce3+ ions. Compared with commercial Tb3Ga5O12 (TGG), CSGG is also paramagnetic, but its magneto-optical properties are better. The Verdet constants of CSGG in 532, 635, 1064, and 1550 nm are -380.0, -258.8, -47.5, and -22.4 rad/Tm, respectively, which are from 1.2 to 2.0 times that of TGG. Moreover, the CSGG crystal has high transmittance in 1500-2300 nm to make up for the poor transmittance of TGG crystal in this band. Also, considering its low raw material cost, the CSGG crystal presents promising application potential. It could be qualified as an essential material for magneto-optical isolators, circulators, and switches within the visible to mid-infrared band.

Abstract ：
The chiral sillenite Bi25FeO40 exhibits versatile properties including electro-optics, magneto-optics, optical rotation, and photorefraction, showing great potential in multi-functional magneto-optical devices. However, the weak magnetism of this crystal leads to a poor magneto-optical property, which is extremely hindering its practical applications. Combining with the sillenite structure, the formation energy and the magnetic-optical effect are calculated based on density functional theory. The codoping of strongly magnetic Co and Fe ions is predicted to enable high doping concentrations. The hybridization between Bi 6p orbitals and Fe/Co 3d orbitals significantly enhances the optical transition and thus greatly improves the magneto-optical properties. The millimeter-sized Bi26-x-yCoxFeyO40 crystals are successfully prepared by hydrothermal methods. The characterizations on structure, TG-DSC, magnetism, and magneto-optical effect confirm the theoretical predictions that the Co-Fe codoped crystals maintain the chiral bismuth ferrite structure with multifunctional properties and high thermal stability. The Co-Fe codoping significantly enhances the magnetism and magneto-optical properties of Bi25FeO40 crystal. The magnetization of Bi19.0Co3.5Fe3.5O40 increases by 27 times and the magneto-optical effect of Bi19.8Co3.0Fe3.2O40 at 720, 777, 1288, 1388, and 1790 nm are greater than Bi:YIG and undoped Bi25FeO40. Bi26-x-yCoxFeyO40 crystals with enhanced magneto-optical properties by Co-Fe codoping are promising for novel multifunctional magneto-optical devices. DFT calculation is a feasible way for predicting the magneto-optical Faraday rotation angle of Bi25FeO40 sillenite crystal. A series of cubic Bi26-x-yCoxFeyO40 crystals are prepared by hydrothermal method. Bi19.8Co3.0Fe3.2O40 crystal has a stronger magneto-optical effect than the commercial Bi:YIG crystal in 1500-1800 nm. It opens up new possibility for the creation of novel multiple functions magneto-optical devices. image

Abstract ：
This paper focuses on the magneto-optical properties of sillenite Bi25FeO40 crystals rather than optofractive, optoelectronic, piezoelectric and other properties. The Bi25FeO40 crystals with heavy Co3+ and Fe3+ co -doping were successfully grown into centimeter size by the top-seeded solution growth method. The thermal stability of crystal structure was improved. Annealing in oxygen atmosphere can greatly reduce oxygen vacancy defects, thereby improving the transmittance of the crystal. After doping Co3+ and Fe3+, Fe -O-Fe, Fe-O-Co and Co-O-Co superexchange interactionis formed in the crystal, which greatly enhances the magnetism of the crystal. Not only the magnetic but also the magneto-optical properties were significantly enhanced by co-doping Co3+ and Fe3+.(c) 2023 Published by Elsevier B.V.

Abstract ：
Bi3+-doped iron garnet crystals (Bi:RIG) have received extensive attention for their excellent magneto-optical properties. The quality of garnet crystals has a great relationship with mismatch in the lattice and thermal expansion between crystals and seeds. Compared with TGG seeds, Sc,Ga:YIG is more suitable as the seed for growing Bi:(HoEu)IG crystals. The crystal quality and match in the lattice and thermal expansion have been discussed. The as-grown Bi:(HoEu)IG crystal has a specific Faraday rotation angle of -467 degrees cm-1 and shows a strong magneto-optical effect.
