► Li2Tb4(MoO4)7 crystal was grown by the Czochralski method. ► Li2Tb4(MoO4)7 crystal has larger Verdet constants than those of TGG crystal. ► Li2Tb4(MoO4)7 crystal may be a candidate material for magneto-optical devices. Li2Tb4(MoO4)7 crystal with sizes of ∅20×26mm was grown by the Czochralski method. X-ray powder diffraction was carried out and the lattice parameters were calculated, which showed that the single crystal belongs to tetragonal system. Absorption spectrum in the wavelength range of 400–1600nm and weak absorption at 1064nm were measured, which indicates the crystal has low absorption coefficient at 600–1500nm regions. The Verdet constant of Li2Tb4(MoO4)7 crystal at 532nm comes up to −347rad/mT, which is as 1.8 times as that of TGG reported.
