The Fe3Pt alloy thin films were grown on MgO substrates at the various growth temperatures by e-beam evaporation in a high vacuum. The magnetic properties such as saturation magnetization, coercivity, magnetic anisotropy etc. of the Fe3Pt alloy thin films were studied as a function of temperature varying in the range of 80K to 600K. At low temperature (80K), the Fe3Pt films possessed giant cubic magnetic anisotropy (K1≈7×106 erg/cc and K2≈2.2×107 erg/cc). The magnetic anisotropy constants of Fe3Pt films were found to decrease slowly with temperature and vanished at Curie temperature. The Curie temperature of Fe3Pt thin films were also studied as a function of ordering. It was observed that higher ordered sample exhibited lower Curie temperature. PACS : 75.30.Gw
