Effect of substrate inclination on the magnetic anisotropy of ultrathin Fe films grown on Al₂ O₃(0001)

We have investigated the effect of substrate inclination on the in-plane magnetic anisotropy of ultrathin Fe films grown on Al₂O₃(0001). For Fe films grown on flat Al₂O₃ substrates, no preferred direction of magnetization exists in the film plane due to the three equivalent epitaxial orientations of Fe(110) that form. However, for Fe grown on an inclined Al₂O₃ substrate, a uniaxial anisotropy appears that is parallel to the step edges. The anisotropy increases in magnitude with decreasing Fe thickness and growth temperature, and as the surface morphology changes from being rough to being smooth. We attribute the uniaxial anisotropy to the effective demagnetization field caused by the surface corrugation.Yu Shiratsuchia, Yasushi Endo, and Masahiko Yamamoto, Bader, S.
