Probing the Magnetism of Nanostructures buried in Metallic Surfaces: an Ab-Initio Study — •Oleg O. Brovko and Valeri S. Stepanyuk — Max-Planck-Institut für Mikrostrukturphysik, Weinberg 2, D-06120 Halle, Germany

For a long time it has been known, that the apparent transparency of metallic surfaces for electronic states can be utilized to detect and study buried nanostructures. We show that it is as well possible to study the magnetic properties of nanostructures buried up to 20Å deep in metallic surfaces. Our ab-initio calculations reveal the possibility of detecting magnetic properties of 3d atoms and small clusters embedded into a metallic surface and even determining the magnetic coupling between them.
