Abstract
We report Magnetic Circular X-ray Dichroism (MCXD) measurements of ult rathin monolayers (ML) and bulk-like Co films grown on a Cu(100) surfa ce. No increase is observed in the orbital magnetic moment of the Co a toms for the ultrathin films in contrast to expectations due to symmet ry lowering on the surface. We developed a new ac field modulated MCXD -susceptibility technique permitting accurate measurements of the crit ical temperature T(c). At about 1.8 ML, T(c) suddenly increase by more than 150 K when the film structure changes from hetero- to homoepitax ial growth.
