Abstract
We show that superparamagnetic Co clusters supported on a Au(lll) surface e xhibit a strong variation in perpendicular magnetic anisotropy with cluster size, which can be ascribed to electron localization at the perimeter of t he clusters. The reduced dimensionality of such sites leads to drastic chan ges in the 3d electronic structure resulting in an increased orbital magnet ic moment and a temperature-dependent 3d band occupancy.
