Abstract

The magneto-optical Kerr rotation of thin ferromagnetic film (Co, Ni, and Fe) is studied experimentally and theoretically. The Kerr rotation of magnetic/air structures is found to be enhanced a lot even when the thickness of magnetic layer is very small. Numerical calculation also indicates that if a thin magnetic layer is sandwiched between two dielectric layers of the same optical constants, the Kerr rotation does not drop as the thickness is decreased.
