TbFeCo/(Pt,Pd,NdCo)多層膜の磁気及び磁気光学特性  [in Japanese] Magnetic and Magneto-Optical Properies of TbFeCo/(Pt,Pd,NdCo) Multilayers  [in Japanese]

The magnetic and magneto-optical properties of TbFeCo/ (Pt, Pd, NdCo) multilayer films prepared by sputter-deposition are discussed in conjunction with the multilayer structure. It is most likely that Pt, Pd, and NdCo play a part in increasing the moment of the transition metals in their sub-lattices. The effect of the Pt layers on the polar Kerr spectra is signifiant at ultraviolet photon energies. A dramatic increase in the magnetic moment and the ωσ_<xy>" spectrum for the TbFeCo/Pt multilayer strongly suggest the existence of interfacial FePt alloy layers, and this possibility is supported by a simulation of the Kerr spectra.
