Abstract
We have investigated the electronic and magnetic properties of Co thin films epitaxially grown on Au(111) substrate by spin- and angle-resolved photoelectron spectroscopy. At Co/Au(111) interface, we observed strong mixing between Au 5d and Co 3d states resulting in the spin polarization of Au 5d states and the increase in Co 3d orbital parallel to the surface, which causes the perpendicular magnetic anisotropy of Co films. The electronic structure of Co thin film in low coverage region is different from that of bulk hcp Co and it becomes closer to those of the bulk as film thickness increases. Reorientation of the magnetization direction was observed at about 6 ML, the origin of which is qualitatively explained by the increasing contribution of Co 3d orbitals perpendicular to the surface.
