Growth　conditions　for　pure　and　Al3+-doped　Tb3Ga5O12　garnet　crystals　by　the　Czochralski　method　have　been　established.　The　growth　protective　atmosphere,　changes　in　the　lattice　parameters　with　various　dopant　concentrations,　segregation　coefficient　of　Al3+　in　Tb3Ga5-xAlxO12　crystal,　absorption　and　transmission　spectra　in　the　wavelength　range　of　400-1100　nm　as　well　as　the　Faraday　rotation　and　magneto-optical　figure　of　merit　in　532　nm　are　investigated.　©　2007　Elsevier　B.V.　All　rights　reserved.
