Abstract
Using X-ray Magnetic Circular Dichroism, the spin and orbital magnetic mome nts were determined through the sum rules for ultrathin (2-4 ML) films of 3 d elements on Cu(001). The fct Co ultrathin films, contrary to the fct Ni, show an enhancement of the orbital moment. The influence of direct coupling in Fe/Ni and Co/Fe bilayers is investigated. In Fe/Ni, an enhancement of t he Ni (15 ML) orbital moment is observed. The easy axis of the Fe (3 ML) ma gnetisation changes from out of plane to in plane by capping it with Co.
