摘要：

The dispersion of the Verdet constant of LiY1.0-xErxF4 crystals was evaluated from 190 nm to 500 nm for different doping concentrations of Er ions. A 15% doping concentration yielded a high Verdet constant of 54.5 rad/(T center dot m) at 193 nm. This value can be explained by the contribution of the diamagnetic term associated with LiYF4 and the paramagnetic term of the Er ions. Although the LiYF4 crystal yielded a lower value of -36.6 rad/(T center dot m) at 193 nm from Er-doped LiYF4, it can be used in the vacuum-ultraviolet region because of its high transmittance at wavelengths longer than 120 nm.
