摘要：
The effect of seed layers on the magnetic and structural properties of FePt thin films was investigated. For the case of Cr(200) seed layer, no ordered L1(0)-FePt phase in (001) orientation was observed. The insertion of a thin MgO barrier between the Cr and FePt layers improved the perpendicular magnetization orientation of L1(0)-FePt by limiting diffusion of Cr into the FePt magnetic layer. Ordered L1(0)-FePt thin films can be developed on Pd[100] at high substrate temperature with the lattice mismatch of below 1% and therefore low roughness compared to MgO or Cr seed layers.
