Abstract
The anisotropy contribution of itinerant electrons confined to a quantum-well potential is calculated and compared with the quasi-ionic contribution due to virtually bound electrons. The easy magnetization direction of the non-L-S quantum-well electrons lies in the plane, and the magnitude of the anisotropy, maximally of order 10 J/m3, is too weak to explain anisotropies encountered in practice. This means that itinerant 3d anisotropy in bulk materials and thin films is associated with Hund's rules-type ionic Contributions.
