Koopmans et al. discussed a ±90° Kerr rotation for the case of s-polarized input light for normal incidence and a magnetiza-tion perpendicular to the photon polarization. Note, we define the Kerr rotation as the relative change of polarization directions of reflected to incident photons. Thus, K = E.,(ui)IEs(ui) and this yields the expected result of = O for the transversal Kerr geometry (polarization perpendicular to the in-plane magnetization).
13. Note, in magneto-optics the observation of A/ = ±1 for dipole transitions is not required due to the addition of spin-orbit interaction. Furthermore, due to hybridization the discussed bands contain beside the p character also some /-electron character.
