Magnetic properties of ultra-thin Mn films grown on (0 0 1) BCC Fe

Abstract : The structural and magnetic properties of ultra-thin Mn films epitaxially grown on (0 0 1) Fe are investigated by X-ray absorption and magnetic circular dichroism. On the one hand, Mn is observed to grow in a BCT structure up to 2 atomic planes. A ferromagnetic order within the Mn layer and a ferromagnetic Mn/Fe coupling are observed. Above 2 monolayers, the Mn structure changes and the ferromagnetic order disappears. However, this structural transition is due to the increase of the Mn film dimension from 2D to 3D, but not due to the structural transition. On the other hand, the magnetic properties below 2 monolayers are observed to drastically change when the Mn films are oxidized. The Mn/Fe coupling observed to be ferromagnetic in unoxidized Mn films becomes antiferromagnetic when the Mn film is oxidized.
