Magnetic thin films and nano-structures

The magnetic properties of of thin films and nano-structures are of high importance in magnetic data storage (hard disks as well as magnetic random-access memory) and future spin-electronic devices. Thin films and nano-structures of a magnetic material show fundamentally different magnetic and electronic properties compared to their bulk counterparts, such that patterning of the material allows wide tailoring of the coercivity, magnetic anisotropy, magnetic moment, magnetic exchange, magneto-resistance and many more properties. We use in situ self-organisation of the magnetic material by controlled deposition and a proper choice of the substrate to explore the magnetic and electronic properties of the nano-structures by magneto-optical Kerr effect and Scanning Tunneling Microscopy.
