摘要：

The magnetic properties of Mn ultra-thin films epitaxially grown on (001) bcc Fe are studied by soft-X-ray magnetic circular dichroism. At room temperature, the Mn growth is two-dimensional without interdiffusion in Fe, as checked by RHEED and Auger spectroscopy. A net Mn magnetic moment is observed in the Mn thickness range up to 2 monolayers. We find that the Mn/Fe interfacial coupling is definitely ferromagnetic. In this range, the magnetic moment carried per Mn atom is found to be about 1.7 mu(B), which is much smaller than the value of 3 mu(B) predicted for ferromagnetic Mn ultra-thin films.
