Structural, electronic and magnetic properties of ultrathin epitaxial manganese films

Jiaming Song
This thesis focuses on low-dimensional materials, namely ultrathin Mn films and graphene, on metallic substrates. Their surface structure as well as electronic and magnetic properties were investigated by scanning tunneling microscopy (STM) using a ferromagnetic ring-shaped bulk iron probe with in- plane magnetic sensitivity at room temperature. The surface of a few atomic monolayer thick antiferromagnetic Mn films with expanded face-centered tetragonal structure on Co/Cu(001) exhibits a submicrometer-scale layerwise contrast in scanning tunneling spectroscopy (STS)...
