Abstract

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.
