Study of Fe/Mn/Fe<f>(0 0 1)</f> multilayers by means of scanning tunneling microscopy/spectroscopy

To elucidate the magnetic properties of a magnetic multilayer film, an understanding of the local geometry, electronic structure, and possible intermixing at the interfaces is of utmost importance. By gradually increasing the Fe coverage on the Mn<f>(0 0 1)</f> film, we obtained this information on the interface region by means of Auger spectroscopy and scanning tunneling microscopy/spectroscopy. Intermixed atoms and various geometries and density of states are found to exist in this system. [Copyright &y& Elsevier]
