Lattice Parameter Dependence of Refractive Index and Dielectric Constant of Czochralski Grown Rare-Earth Garnet Single Crystals in Solid Solution

The refractive index and dielectric constant of garnet single crystals grown by the Czochralski method were measured. New results were obtained which revealed that both the refractive index and dielectric constant increased with the increase of their lattice parameters depending on their ionic radius of rare-earth ions.
