Surface magnetism of a Ni overlayer on a Cu(001) substrate

Self-consistent spin-polarized energy-band studies of a Ni monolayer on each side of a five-layer Cu(001) substrate show that the Ni overlayer is not magnetically "dead"; its moment of 0.37${\mathrm{\mu }}_{\mathit{B}}$/atom is 40% lower than the Ni bulk value and is similar to the behavior found earlier by Wang and Freeman for the surface layer of a nine-layer Ni(001) film.
