Research Interests

The current research interest of our group is in the field of Strongly Correlated Materials with novel electronic properties, such as High Temperature Superconductors, Topological Kondo Insulators/Kondo Insulators and Heavy Fermions as well as Low Dimensional Magnetic systems. It is our goal to contribute to a better understanding of the basic physics of these correlated materials by performing concerted experimental studies which may help to clarify the origin of complex magnetism and superconductivity in these systems. For this purpose, microscopic and macroscopic magnetic and electronic properties of these materials are investigated by means of a combination of different complementary experimental techniques, including magnetization and transport (using PPMS/SQUID) and Neutron Diffraction (using WISH, D2B, D20 beamline), Neutron Scattering (using MARI, MERLIN, IN4, IN6 beamline), Muon Spin Rotation (using MUSR, EMU, HI-Fi, ARGUS beamline) measurements. Our group has a strong record in obtaining competitively awarded beam time at some of the world’s leading international facilities including ISIS (United Kingdom) and the Institute Laue Langevin (Grenoble, France). Research collaborations currently exist with groups from around the world including the United Kingdom, Japan, South Africa, France, Germany, and India. The work of the group is regularly published in leading international journals and is frequently represented globally at conferences.
