Abstract
Self-consistent local-orbital (SCLO) calculations were performed for a monolayer of Ni on a three-layer Cu{100} substrate. The magnetic moment of the supported monolayer was found to be , compared with the value obtained for the free monolayer. Factors which suppress the magnetism include hybridization of Ni and Cu orbitals, and surface charge transfer. Energy bands computed for the Ni/Cu sandwich include surface-state bands which closely resemble those obtained earlier for the free Ni monolayer, except for their much smaller exchange splittings.
