摘要：

FeMn/Ni/Cu(001) bilayer films are grown epitaxially and investigated by photoemission electron microscopy and magneto-optic Kerr effect. We find that as the FeMn overlayer changes from paramagnetic to antiferromagnetic state, it switches the ferromagnetic Ni spin direction from the out-of-plane to an in-plane direction of the film. This phenomenon reveals the mechanism of creating magnetic anisotropy by the out-of-plane spin frustration at the FeMn-Ni interface.
