Abstract
Atomically thin Co/Pt(1Â 1Â 1) interfaces grown at different temperatures are characterized by very different values of perpendicular magnetic anisotropy as a consequence of the local structure and coordination. Here we present a study of the structural, magnetic and electronic properties for interfaces grown in UHV onto clean Pt(1Â 1Â 1) in different kinetic conditions. When one monolayer of Co is deposited at 540Â K a thermally activated exchange reaction leads to a sharp Pt-Co double interface giving rise to a strong increase of the magneto-optical response with respect to the Co monolayer deposited at room temperature. The results are interpreted in terms of atomic hybridization as detected by valence band photoelectron spectroscopy.
