Magneto-Optic Rotation Enhancement in Thin Magnetic Films

摘要

The effects of an antireflection coating of ZnS upon the magneto-optic rotations in a thin semitransparent NiFe film was investigated experimentally. The magneto-optic amplitude components, Kerr and Faraday, are observed to be augmented or diminished by the ZnS coating, depending upon the polarization mode of the incident light and the orientation of the coated specimen. A simple theoretical model accounts for the phenomena observed in the several experimental cases. (Author)
