N2 - Faraday rotation spectra of Co/Pt multilayers were obtained in the region including Co M2,3 and Pt N6,7 absorption edges by using multilayer polarizers, and were transformed to magnetic circular dichroism (MCD) spectra by Kramers-Krönig analysis (KKA). From the dependence of the rotation angle on the layer thickness, it was suggested that the magnetization of Co tends to be uniform in Co layers and that of Pt is localized at Co/Pt interfaces. The orbital magnetic moment of Co was estimated to be about 0.17 μB/Co. The similarity of electronic states around magnetized Pt site between Co/Pt multilayers and CoPt3 alloy is suggested by the resemblance of the MCD spectra of both materials around Pt N6,7 edges. In addition, magnetic Kerr rotation of Co/Cu multilayer was measured and was observed around Co M2,3 and Cu M2,3 absorption edges.
