Abstract

The magnetic and magneto-optical properties of TbFeCo/(Pt,Pd) multilayer films prepared by sputter-deposition are discussed in conjunction with their multilayer-structure. The effect of polarized Pt on the polar Kerr spectra is significant at ultraviolet photon energies (~5 eV). A drastic increase in the magnetic moment for the TbFeCo(Pt,Pd) multilayers is observed. This result, together with a model to account for the observed magneto-optical spectra, suggests the existence of interfacial Fe-Pt and Fe-Pd alloy regions
