| Electronic structure and local magnetic moments for the epitaxially grown fcc Fe films included between the Cu(001) substrate and Cu(001) covering layers are calculated. The lattice constant of the Fe film is assumed to be equal to that of Cu homogeneously in the whole film. Interface parts of the Fe film are found to be ordered ferromagnetically, while inner part of the Fe film is obtained as ordered layer-by-layer antiferromagnetically for odd number of layers. For even number of Fe layers the most favourable configuration includes antiferromagnetism of inner layers with two middle layers coupled ferromagnetically. |
