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 
, which is much smaller than the value
of 
predicted for ferromagnetic Mn ultra-thin films.
