GSGG Substrate | Gadolinium Scandium Gallium Garnet Series Crystal Substrate

Gadolinium Scandium Gallium Garnet (GSGG) Substrate is a high-quality single-crystal material with a larger lattice constant (12.554 Å), making it well-suited for magneto-optical thin film applications. Compared to GGG, GSGG incorporates scandium ions, which replace gallium in the crystal structure, leading to improved lattice matching for specific epitaxial films. Its excellent compatibility with bismuth iron garnet (BIG) thin films further enhances its value for advanced optical and magnetic applications. Heeger Materials provides high-quality GSGG substrates with consistent performance for research and industrial needs.
