Fifty-nm-thick Fe75Pt25 thin films have been made on glass substrates by rf magnetron sputtering at room temperature, and subsequently annealed at 300 –700 °C (Ta) for 1 h. The as-deposited Fe3Pt film exhibits high magnetization of 1530 emu/cm3 and a disordered bcc structure, confirmed by high-resolution synchrotron radiation x-ray diffractometry. First-phase transformation from the bcc to disorder fcc structure occurs for samples annealed at 300 °C. With increasing of Ta up to 375 °C, the film displays a nearly disordered fcc phase with low magnetization of 1083 emu/cm3. The fcc phase changes to ordered L12 structure for samples with Ta ≥ 400 °C. The highly ordered L12 phase with magnetization of 1270 emu/cm3 and coercivity of 66 Oe was obtained in Fe3Pt film at 700 °C-annealing.
