Abstract

In this study, the FePt_xPd_{1 - x} (x = 0, 0.25, 0.5, 0.75, 1) (Fe-Pt-Pd) alloy films were prepared by sputtering. The effects of Pt addition content and heat treatment on the microstructure and magnetic properties of polycrystalline Fe-Pt-Pd films are reported. The experimental results show that the ordering temperature of the Fe-Pt-Pd films in this study is lower than that of the Fe-Pt-Pd alloy. After heat treatment at 600 °C for 30 min, the FePt_0.75Pd_0.25 film shows a coercive force of 7.18 kOe and a magnetization of 980 emu/cc. The magnetic properties of the Fe-Pt-Pd films can be adjusted by varying the Pt content in the films. From the observation of transmission electron microscopy (TEM), the improvement of the magnetic properties of the FePt_0.75Pd_0.25 films is believed due to the magnetic coupling effect between the order and disorder phases.
