Garnet films for magneto-optical recording

Abstract

This paper reviews bismuth-substituted ion garnet films for magneto-optical (MO) recording. The influences of doped ions on anisotropy (Ku), compensation temperature (Tcomp) and coercivity (Hc) are discussed. From the viewpoint of practical application the optimum design of disk structure such as reflective layers and thickness of garnet films is also described.
