Abstract
We report a striking sensitivity of the easy magnetization axis in epi taxial Co films upon adsorption of submonolayers of Cu, Ag, Fe, and O if the Cu substrate is a stepped surface slightly miscut from the (100 ) orientation. All adsorbates cause a switch of the easy axis by 90 de grees within the plane. The key role of this switching phenomenon is p layed by the atoms at the step sites and their influence on the magnet ic surface anisotropy.
