The growth and magnetic properties of films of fcc cobalt on Cu(100) substrates has been characterized by a multitechnique approach. The films are ferromagnetically ordered in-plane at temperatures below Tc. The Curie temperature of the films displays a linear dependence with the coverage reaching bulk-like behaviour at coverages of 5–6 monolayers. Spin-polarized photoemission shows that the band structure is already close to that of the bulk at 5 ML. Crystalline Co/Cu superlattices have also been grown on Cu(100) substrates. The magnetic ordering of Co slabs across Cu layers of varying thicknesses, as explored by neutron diffraction, has been found to be antiferromagnetic. When applying an external magnetic field in the plane of the layers, the magnetization shows a complex behaviour related to in-plane anisotropy.
