英文摘要:
Highly transparent Tb2.96Pr0.04Ga5O12 single crystal was grown by the Czochralski (Cz) method. X-ray powder diffraction was carried out, and lattice parameters were calculated, which showed that the single crystal belongs to cubic crystal system. The full width at half maximum of the rocking curve for the crystal was about 28 arcsec that showed the high crystallinity of the crystal. The optical and magneto-optical properties of Tb2.96Pr0.04Ga5O12 are analyzed in detailed. The grown crystal exhibited a very high transmittance, particularly in the visible region. Measurements of the Faraday rotation and Verdet constant spectrum at different temperatures were investigated at VIS-NIR region. The increase in Verdet constant and magneto-optical figure of merit compared to that of TGG shows the superior characteristics of Tb2.96Pr0.04Ga5O12 compared to TGG, indicating that it has great potential to meet the increasing demand for magneto-optical devices in the VIS-NIR region.
