A pyrochlore crystal with magneto-optical effect - Dy2Ti2O7 crystal with 19-20 mm in diameter and 21 mm in length has been grown by the Czochralski method. The lattice parameters were calculated by X-ray powder diffraction, which revealed that the crystal belongs to cubic system. Absorption spectrum was measured in the visible and near-infrared region at room temperature, which indicated the crystal has low absorption coefficient at 600-760 nm. The specific Faraday rotation of single crystal was measured at room temperature in 532, 633, and 1064 nm. The Verdet constant of Dy2Ti2O7 crystal at 633 nm comes up to 183 rad/(m T), which is as 1.4 times as that of TGG reported. (C) 2014 Elsevier B.V. All rights reserved.
