Adsorption and Magnetic Properties of Ultrathin Fe and Ni Alloy Films with an Inhomogeneous Magnetization Distribution

Abstract:

Theoretical description of ultrathin ferromagnetic Fe and Ni alloy film adsorption on a nonmagnetic metal substrate is considered by the spin-density functional method. The conditions for the formation of ultrathin ferromagnetic films stable with respect to island adsorption with a change in the coverage parameter θ and Fe content concentration x are revealed. The equilibrium vacuum gap D_min and the equilibrium film thickness h_min are determined from the minimum of the total interfacial energy. The energy and magnetic characteristics of Fe_xNi_1-x films on close-packed W and Cu surfaces are calculated in dependence on concentration x for different temperatures.
