Efectos magneto-ópticos en interfaces simples y aproximación al caso de multicapas

Abstract

In this work the problem of the interaction of the radiation-matter for the case of structures with magnetic anisotropy, in particular with respect to the magneto-optical Kerr effects in the three magnetic geometries known by reflection (polar, longitudinal and transverse) , This effect allowed to calculate the angular and spectral dependence of the magneto-optical signal Kerr in the simple interfaces of Cobalt Air. The analysis of angular and spectral dependence of the magneto-optical signal Kerr in the three magnetic geometries were obtained, by means of a simulation with the help of the tool Scilab (free software), and the magneto-optical constants experimentally provided by the group of Magnetoplasmónica of the Institute of Microelectronics of Madrid (Spain), which resulted in a series of graphs that relate the magneto-optical signal Kerr with the angle of incidence of the electromagnetic radiation, as well as the relation with the wavelength of the same.
