Lithium　terbium　molybdate　(LiTb(MoO4)(2))　single　crystal　was　grown　by　the　Czochralski　method.　The　lattice　parameters　of　the　crystal　were　determined　by　X-ray　diffraction　analysis.　The　absorption　coefficient　and　the　Faraday　rotation　spectrum　(B=1.07　T)　were　investigated　at　wavelengths　of　400-1500　nm　at　room　temperature.　Verdet　constants　of　LiTb(MoO4)(2)　crystal　at　532-,　633-　and　1064-nm　wavelengths　were　measured　by　the　extinction　method.　The　results　show　that　LiTb(MoO4)(2)　crystal　has　a　larger　magneto-optical　figure　of　merit　than　that　of　terbium　gallium　garnet　at　wavelengths　of　600-1500　nm.
