Quadratic magneto-optical effect in Fe, Ni and Co

摘要

The theoretical analysis of second-order magneto-optical effects is presented. A material anisotropy is introduced by relative permittivity tensor whose components are expressed using Voigt magneto-optical parameter Q and Liss-berger's parameter /. The permeability corresponds to isotropic medium. Three principal configurations are studied according to the magnetization - transversal, polar and longitudinal. The governing wave equation for the field vector leads to four polarization states described by complex polarization vectors. Their components have been derived in closed form. The eigenmode polarization states in planar structures with magnetic ordering (quadratic effects) for the classical materials applied for magneto-optical media (Fe, Co, Ni) are analysed in detail.
