Interpretation of Magneto-Optical and Reflectivity Spectra in Compositionally Modulated Multilayered Fe/Cu Films

Abstract

Anomalous behavior of magneto-optical Kerr spectra in compositionally modulated multilayered Fe/Cu films is analyzed using virtual optical constant calculations. Calculated spectra are in good agreement with experimental results published previously. The enhancement of the Kerr rotation in Fe/Cu films around the absorption edge of Cu is interpreted in terms of the existence of hybrid plasma in these materials.
