Ba3Tb(PO4)(3)　crystals　have　been　grown　by　the　slow-cooling　method　and　the　Czochralski　technique　for　the　first　time　for　magneto-optical　applications.　The　single-crystal　X-ray　diffraction　confirms　that　the　compound　crystallizes　in　the　cubic　system　I　(4)　over　bar　3d,　with　eulytite　structure　with　a　=　10.4484(12)　angstrom,　V　=　1140.6(2)　angstrom(3)　and　Z　=　4.　The　hardness　of　Ba3Tb(PO4)(3)　crystal　is　about　5.5　Moh.　The　temperature　dependence　of　the　magnetic　susceptibility　indicated　that　the　Ba3Tb(PO4)(3)　crystal　exhibits　paramagnetic　behavior　over　the　experimental　temperature-range　2-300　K.　Transmittance　spectra　and　the　Faraday　rotation　have　been　investigated,　which　demonstrate　that　Ba3Tb(PO4)(3)　crystal　shows　a　higher　visible　transparency　than　Tb3Ga5O12　crystal　and　yields　a　Faraday　rotation　comparable　to　that　of　Sr3Tb(BO3)(3)　crystal.　Ba3Tb(PO4)(3)　is　therefore　a　promising　material　in　particular　for　new　magneto-optical　applications　in　the　visible　region.　(C)　2015　Elsevier　B.V.　All　rights　reserved.
