  First principles calculations of the magnetic properties and the
magneto-optical Kerr effect (MOKE) of iron thin films epitaxially grown on the
[001] surface of paramagnetic metals: copper, silver, gold, palladium, and
platinum are presented. The role of hybridization with the substrate is
investigated and it is shown how the relaxation effects influence the complex
Kerr angle. The results are obtained by means of the relativistic
full-potential linear muffin-tin method, and the film is modeled using a slab
geometry within a supercell technique.
