Resumen:
In this paper we are interested in the magnetic properties of Mn/Cu/Mn and Mn/Ni/Mn slabs as a function of Mn coverage at T = 0 K. A tight-binding parametrized Hamiltonian with s, p and d orbitals is used and the appearance of spillover is accounted for by enlarging the local basis at the surface and vacancy sites. Large magnetic moments on the Mn atoms and competing ferro and antiferromagnetic configurations are obtained.
