Optical and magneto-optical properties of {Co0.45Fe0.45Zr0.1/a-Si} multilayers

Abstract The optical and magneto-optical (MO) properties of {CoFeZr( x )–aSi( y )} n and {CoFeZr( x )–SiO 2 ( y )} n composite films with multilayer structure were investigated. It was shown that the form and magnitude of the MO spectra strongly depend of the magnetic and non-magnetic layer thickness and component of non-magnetic material. The MO spectra were analyzed in the framework of the effective-medium approximations and macroscopic Fresnel magneto-optics to ultrathin layers.
