Abstract
The interfacial properties of fcc-Fe/Cu(111) superlattices are investigated by the first principles all-electron linearized augmented plane wave method in the local spin-density functional approximation. For the paramagnetic phase an interface state located at 2.61 eV below the Fermi level at the K ̄ point of the two-dimensional Brillouin zone is obtained and it develops extending along the K ̄ − Γ ̄ direction. This is consistent with the experimental observation.
