摘要：
The composition dependence of the degree of chemical order S and uniaxial magnetic anisotropy energy K-u has been investigated for FePt (001) and FePt (110) films deposited at the substrate temperature T-s = 300 degreesC, and the optimum compositional region for L1(0) ordering in FePt (110) films has been compared with that in FePt (001) films. It has been found that high S and large Ku are obtained around the stoichiometric composition for FePt (110) films, whereas they are obtained around an off-stoichiometric Pt-rich composition for FePt (001) films, indicating that the difference in optimum compositions for achieving highly ordered structure between FePt (001) and FePt (110) films at reduced temperature.
