I study the different magnetic behaviors of Fe, Co and Ni with respect to bulk properties when forming superlattices with Cu and when one monolayer is deposited on Cu(001). I perform spin polarized calculations using a self-consistent tight binding Hamiltonian and obtain the contribution to the magnetic moment coming from the different orbital symmetries. This information is nowadays experimentally available. I show that the magnetic properties studied can be explained by a qualitative analysis using model paramagnetic densities of states. The distinct magnetic behaviors are essentially due to band filling.
