摘要：

The effects of a TiN intermediate layer on the microstructure and magnetic properties of the FePt films were investigated. With introducing TiN intermediate layer the chemical ordering and magnetic properties of FePt films significantly improved. The FePt film with 5nm TiN exhibited a large perpendicular anisotropy and smaller opening up of in-plane hysteresis loop with out-of-plane coercivity of 13.7 kOe and in-plane coercivity of 0.24 kOe. Moreover, with doping C and SiOx, FePt film with coercivity around 20 k0e, a single layer structure, and small FePt grain size of 5.6 nm in average diameter was obtained.
