摘要：

The step-induced uniaxial magnetic anisotropy of fcc Co films grown on a curved Cu(001) substrate was investigated in the vicinal angle range of 0 degrees to 6 degrees. The anisotropy strength was found to depend linearly on the step density, indicating that biaxial strain due to in-plane lattice misfit is not the origin of the step-induced anisotropy. By performing Cu adsorption experiments, we found that the magnetization easy axis switches by 90 degrees when the Co steps are decorated with similar to 1 atomic row of Cu per step, independent of the step density.
