L1 0-FeNi films were grown by alternate monatomic layer deposition on Au-Cu-Ni buffer layers at several substrate temperatures (T s), and the relation between the uniaxial magnetic anisotropy energy (K u) and the long-range chemical order parameter (S) was investigated. A large K u of (7:0 ±0:2) × 10 6 erg/cm 3 and S of 0:48 ±0:05 were obtained. The value of K u was larger than those reported previously for artificially synthesized FeNi films. It was first found that both K u and S increased with T s, and K u was roughly proportional to S.
