Abstract

The present paper discusses the interfacial structure and the effect on the magnetic and magneto-optical properties in TbFeCo/Pt multilayer films, in contrast with Fe/Pt multilayers. Both the magnetic and magneto-optical properties are explained well when an interfacial region very similar to an Fe-Pt alloy is assumed. Low angle X-ray diffraction analyses reveal that the Fe-Pt alloy-like interfacial regions are formed mainly on top of TbFeCo layers, but little on Pt layers, ωσ_xy spectra indicate that polarization of Pt in the interfacial region is different from that in Fe/Pt multilayers
