Abstract

Fully-relativistic spin-polarized local spin density calculations are performed for an Au covered Co monolayer on Au(111). In good agreement with experiments (i) the enhancement of perpendicular magnetic anisotropy for the capped Co layer, and (ii) a characteristic maximum in the anisotropy energy for one covering Au layer are obtained. The close relationship found between the anisotropies of orbital magnetic moments and the anisotropy energies supplies a partial interpretation of our results in terms of familiar perturbation theory. By using this framework the anomalous behavior of the magnetic anisotropy energies can be well explained due to changes in the interfacial hybridization between Co and Au.
