Magneto-Optical Effects in Nanostructures with Spatial Modulation of Magnetization

Abstract

A new way of detecting the periodically modulated magnetization of ferromagnetic materials is proposed. The technique is based on measuring magneto-optical effects in a magneto-plasmic nanostructure and their dependence on the period of modulation of magnetization. It is shown that the magnitude of magneto-optical effects depends on the spatial phase shift between the periodically modulated magnetization and the plasmon lattice. This dependence is harmonic and allows determination of the period of modulation of magnetization.
