Magnetic Nanomaterials

Magnetic nanomaterials and their assembly in highly correlated structures are of great interest for future applications as e.g. spin-based data storage media and as material for magnon-spintronics. These systems exhibit unique physical properties like superparamagnetism or symmetry breaking emerging due to their limited size. Individual nanomaterials can be combined as building blocks for so called superstructures where the combination of the different functionalities creates a novel multi-functional system, e.g. with magneto-plasmonic properties.

Our research activities focus on the fundamental structural and magnetic research on such objects and their functionalization. For the investigation we make use of different complementary measurement methods: AFM, microresonator FMR, X-ray and neutron scattering (SAS, GISAS, in-situ GISAXS, XRR, PNR, STXM), SEM, SQUID, TEM.
