Research Interests

1. Development of scattering methods:
   - polarised neutron scattering
   - reflectometry and grazing incidence small angle scattering GISANS
   - neutron spectroscopy with polarisation analysis
   - magnetic and anomalous synchrotron x-ray scattering
   - high energy (> 100 keV) synchrotron x-ray diffraction

2. Magnetic nanostructures, e. g. transition metal or rare earth thin film systems and laterally patterned systems:
   - magnetic ordering phenomena,
      e.g. domain structures, magnetisation densities within nanoparticles
   - proximity effects, e.g. exchange bias
   - remagnetisation kinetics
   - interaction between nanoparticles

3. General solid state magnetism:
   - magnetic structure and excitations
   - phase transition
   - frustration
   - disorder

4. Highly correlated electron systems, e. g. perovskite or spinel derivated transition metal oxides or sulfides:
   - complex ordering phenomena,
      e.g. charge-, lattice-, spin- and orbital order
   - magnetic and lattice excitations
