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, ωσxy spectra indicate that polarization of Pt in the interfacial region is different from that in Fe/Pt multilayers
