Abstract
The magnetic behavior of monolayer and submonolayer quantities of Mn adsorbed on an Fe(100) surface is studied using the element-specific magnetic circular x-ray dichroism (MCXD) method in absorption. The shape of the Mn-MCXD spectrum for 0.02 monolayer coverage agrees well with a recent calculation for high-spin Mn if experimental broadening is taken into account. Also the size of the MCXD effect indicates a large net magnetic moment, with the asymmetry at the edge reaching 80% of the value predicted by the theoretical spectrum for the atomic configuration. The sign of the Mn moment is antiparallel to the Fe substrate. With increasing coverage the net Mn magnetic moment rapidly decreases and vanishes for a complete monolayer Mn/Fe(100).
