摘要：

We investigated the thickness and composition dependence of perpendicular magnetic anisotropy (PMA) in L1(0) Fe1-xPtx (x = 0.4, 0.5, and 0.55) films. The FePt films with different thicknesses of 35 and 70 A were grown at the substrate temperature T-s = 300 degrees C by molecular beam epitaxy coevaporation technique. A (001)-oriented epitaxial L1(0) FePt film was grown on the thin (001)oriented fcc Pt layer, while a poorly crystallized FePt film was formed on the (111)-textured Pt layer. Our results showed that, at a fixed thickness of 70 A, the PMA of FePt alloy films is enhanced as Pt content increases from 40% to 55%. (C) 2011 American Institute of Physics.
