Magnetic properties of epitaxial Fe films on MnPt/Fe(100)

Magnetic properties of epitaxial Fe films on MnPt/Fe(1 0 0) were measured using X-ray magnetic circular dichroism (XMCD) and Mott electron spin polarimetry (SP). Surface sensitive secondary electron spin polarization images revealed the magnetization orientation of the Fe overlayers with respect to that of the substrate Fe crystal that was measured with bulk-sensitive XMCD. The magnetic domains of the Fe overlayer are influenced by the substrate magnetic domain structure, giving a clear evidence of the magnetic interaction between the Fe overlayer and the substrate Fe through the antiferromagnetic MnPt film.
