Paper Abstract

Nano-granular Fe50Pt50-Ag composite films are fabricated by annealing the precursor multilayer. Magneto-optical polar Kerr effect and optical constants of these films are measured with photon energy in the range of 1.4 eV to 6.8 eV. Upon considering the multiple reflection and optical interference effect caused by substrate, the diagonal and off diagonal elements of dielectric tensor are calculated out. Plasma resonance of Ag gives an absorption peak at around 3.8 eV. However, the Kerr effect does not show an obvious enhancement at this Ag plasma edge. The optical interference effect and granular structure of these films move the negative peaks in Kerr effect to the lower energy side.
