| Abstract: | L10 ordered FePt thin films have drawn considerable attention as a potential ultra-high density magnetic recording material, due to its large magnetocrystaltine anisotropy energy, high coercivity, high energy product, high Curie temperature, and excellent resistance of corrosion. In this paper, the recent researches in FePt films field are introduced in detail, the mechanisms of reducing the ordering temperature, keeping grain size, decreasing the exchange interaction, controlling the easy axis orientation are also discussed carefully. Finally, the future of its application in the magnetic storage is analyzed. |
