Description

SGGG Crystal (Ca-Mg-Zr Doped Gadolinium Gallium Garnet), professional substrate material specially applied for epitaxial growth of bismuth iron garnet thin films, high optical uniformity and stable crystal lattice structure for magneto-optical devices.

Gadolinium gallium garnet (GGG) substrates, one of the earliest developed materials for use as substrates, are unsuitable due to their extremely small lattice constants. As a result, SGGG crystals, which use calcium, magnesium, and zirconium as substitution ions, are more suitable as substrates for bismuth-iron garnet epitaxial films.
