ABSTRACT
With continuous variable composition, an artificial pseudomorphic template of 1 ML Cu1-xAux was achieved by epitaxial growth on Cu(001), in which the magnetic anisotropy and the spin reorientation transition of Ni films were investigated in situ. The result clearly indicates that the strain induced protruding nanostructures at the interface dominates in tuning the magnetic anisotropy, while the interface chemistry plays a minor role.
