摘要
The ferromagnetic/antiferromagnetic interfacial interaction was investigated in thin Fe films grown on stepped Cr(001) with the steps parallel to the [100]direction. Above the Neel temperature of the Cr, the atomic steps induce a uniaxial magnetic anisotropy with the easy axis parallel to the step edges. Below the Neel temperature, the Fe-Cr interfacial interaction favors the Fe magnetization perpendicular to the step edges. The competition between the Fe-Cr interaction and the step-induced magnetic anisotropy re suits in an in-plane 90 degrees magnetization switching from perpendicular to the step edges at low step-density to parallel to the seep edges at high step density.
