An anomalous magneto-optical Kerr effect in Pd-based multilayers

In this paper we present the calculated magneto-optical Kerr rotation spectra of Fe/Pd and Co/Pd multilayers based on two different assumptions. Firstly the spin-polarization of the Pd layers and its additional magneto-optical Kerr effect in Fe/Pd and Co/Pd multilayers are assumed negligibly small. Secondly the Pd layer is assumed to be spin-polarized. The calculated spectra with the latter assumption agree with the measured spectra by modifying the parameters. The Pd layers are suggested to induce an additional magneto-optical Kerr effect and thus enhance magneto-optical Kerr effect in these multilayers.
