Abstract

Single and double spin-flip energies are calculated for n layers of homogeneously disordered FecCO1-c on Cu(100) with n varying between three and six. It is found that these spin-flip energies describe quite accurately the type of most favourable magnetic coupling between the magnetic layers and also give a rather detailed picture for the occurrence of certain magnetic configurations. A phase diagram of ferromagnetic versus antiferromagnetic coupling with respect to the number of layers and Fe concentration turns out to be closely related to the phase diagram of the reorientation transition in this system.
