Na2Tb4(MoO4)(7)　crystals　have　been　grown　by　the　Czochralski　technique　for　the　first　time　for　magnetooptical　applications.　Structure　refinement　of　XRD　data　confirms　that　the　compound　crystallizes　in　the　tetragonal　system　I4(1)/a,　with　scheelite　structure.　The　as-grown　crystal　exhibits　moderate　thermal　stability　and　weak　thermal　expansion　anisotropy　(alpha(c)/alpha(a)　approximate　to　1.08),　and　the　hardness　is　about　4.7　Moh.　Transmittance　spectra　indicated　that　the　Na2Tb4(MoO4)(7)　crystal　presents　a　high　transparency　from　600　nm　to　1500　nm　after　annealing　in　02　atmosphere　at　973　K　for　20　h.　The　Faraday　effect　and　the　temperature　dependence　of　the　magnetic　susceptibility　have　been　investigated,　which　demonstrate　that　the　Na2Tb4(MoO4)(7)　crystal　exhibits　paramagnetic　behavior　over　the　experimental　temperature-range　2300　K　and　yields　a　Faraday　rotation　which　is　about　1.6　times　as　large　as　that　of　Tb3Ga5O12　crystal.　Na2Tb4(MoO4)(7)　crystal　is　therefore　a　promising　Faraday　material　in　particular　for　new　magneto-optical　applications　in　the　visible-near　lR　wavelength　region.　(C)　2015　Elsevier　B.V.　All　rights　reserved
