| Abstract(in English) | Analysis of Co/Pt and Co/Pd multilayer films was performed to investigate the dependence of interfacial magnetic anisotropy (IMA) and induced magnetization on the thickness of the laminated Pd or Pt layers. For the Co/Pd multilayer films, as the Pd layer got thicker, the IMA energy increased proportionally on the amount of induced magnetization up to the Pd layer thickness of ～0.8 nm. This suggests that the whole magnetic moment induced in a few Pd atomic layers contributed to the IMA. In contrast, for the Co/Pt multilayer films, this proportional relationship only held when the thickness of the Pt layer was less than ～0.2 nm. Since one Pt monolayer is 0.225 nm thick, the amount of IMA energy in the Co/Pt films is proportional to the number of Pt-Co atomic contacts. This difference between Co/Pt and Co/Pd multilayer films is attributed to the difference in the latent ferromagnetism between Pt and Pd. |
