OST Photonics GSGG Substrates GGG (12.373) has a similar lattice constant of YIG (12.376), it is widely used as the substrate material of YIG magneto-optical thin film. However, in order to improve the magneto-optical optimum value of magneto-optical thin film, sometimes it is necessary to select a single crystal substrate with a larger lattice constant. GSGG (12.554) is that the 2 Ga of the octahedron in the GGG crystal are replaced by Sc with a larger ionic radius, thus having a larger lattice constant.
