Abstract

Bi substituted garnet films are promising materials for magneto-optic devices because of their high Faraday rotation. This paper discusses the parameters and growth conditions of epitaxial garnet films for optical isolators at 800 nm wavelength region. Garnet films with 2°/μm specific Faraday rotation and relatively low saturation magnetization were obtained.
