摘要：A substrate for forming a magnetic garnet single crystal film by liquid phase epitaxy, a method for forming a single crystal film by crystal growth using the substrate, a single crystal film formed by the method and an optical device are all claimed. The substrate (2) has a base substrate (10) composed of a garnet single crystal unstable to the flux used for the liquid phase epitaxy and a buffer layer (11) formed on the base substrate (10) and composed of a garnet single crystal thin film stable to the flux.
