Research Interests

My scientific activity centres on investigations of magnetic interactions in intermetallic compounds containing either rare earth (magnetic 4f electrons) or actinide (magnetic 5f electrons) elements. Those compounds show a great variety of magnetic properties such as ferromagnetic or antiferromagnetic order, mixed valence or heavy fermion behaviour, which may result in a superconducting or insulation groundstate. I mainly used inelastic neutron scattering techniques for these investigations, especially for the study of the interplay of magnetism and superconductivity in unconventional superconductors. But I also performed neutron diffraction investigations, transport and magnetisation measurements as well as synchrotron radiation experiments on various samples including thin films. Due to my long-standing collaboration with colleagues from the Institute of transuranium elements (Karlsruhe, Germany), MPI-CPfS (Dresden, Germany), Univ. Wien (Vienna, Austria) and TU Dresden (Germany) I had the pleasure to act as local supervisor for several PhD students. Those collaborations allow me to combine my microscopic investigations with laboratory measurements.
