Abstract

In-plane magnetized FePt films were prepared on MgO (1 1 0) single crystalline substrates by sputter-deposition, and the effects of a buffer layer and substrate temperature during deposition (Ts) on the formation of the L10 ordered structure have been investigated. From the X-ray diffraction patterns, the FePt (1 1 0) and (3 3 0) superlattice peaks of L1 0 phase have been clearly observed for the FePt thin film with an Au buffer layer deposited at Ts = 300°C. High degree of chemical order (S = 0.7±0.1) have been achieved, leading to the large uniaxial magnetic anisotropy Ku of 2.4 × 107 erg/cm 3 with the easy axis along an in-plane direction.
