Abstract

The influence of buffer layers on magnetic properties and structures of FePt (001) films, sputter deposited on MgO at reduced temperature was investigated. The x-ray diffraction (XRD) and transmission electron microscopy (TEM) were used for the structural characterization of the films. Obtaining the L1₀ ordered structure with large perpendicular magnetic anisotropy was found to be possible for the FePt films with and without buffer layers. Without a buffer layer, The degree of long-range order and uniaxial magnetic anisotropy energy was found to increase with increasing lattice mismatch.
