    Fonin Research Group

    Magneto- and spin electronics stand at the boundary between fundamental physics research, materials science and technological applications. Of particular interest here are new classes of magnetic materials as well as the surface and interface properties of magnetic nanostructures. We focus on the investigation of the interplay between structural, electronic and magnetic properties of low-dimensional systems at surfaces.

    Magneto- and spin electronics stand at the boundary between fundamental physics research, materials science and technological applications. Of particular interest here are new classes of magnetic materials as well as the surface and interface properties of magnetic nanostructures. In each specific area the interplay between structural, electronic and magnetic properties of the system under investigation is of prime importance.
