| Abstract(in English) | It was found that the fcc-fct phase transformation temperature of sputtered FePt thin film was reduced by the addition of Cu element. Formation of FePtCu ternary ordered alloy might increase the driving force of the phase transformation and result in the reduction of fcc-fct transformation temperature. Chemical analyses such as TEM-EDX, UPS and EXAFS were performed to investigate the atomic position of Cu atom in the FePtCu film. The results indicated that the Cu atom was substituted for the Fe site of FePtCu fct phase as supposed in the above model. Magnetic anisotropy energy of FePtCu alloy was also estimated by the band calculation and found to be 6.1×10^7 erg/cc, that was about a half of that of FePt alloy. |
