The Scientific Servicegroup "Chemieservice" (Kremer) develops techniques and provides experimental facilities to support all experimental groups of the institute with the characterization of the transport and magnetic properties of new compounds and samples. This objective requires a high versatility of all experimental methods including the development and cultivation of experimental setups to perform measurements on very small samples by contactless methods under inert gas conditions. Available are commercial SQUID magnetometers, ac-susceptometers which allow measurements down to 0.3 K and magnetic fields up to 12 Tesla, a contactless microwave transport method, ac- and dc-electrical transport measurements in magnetic fields up to 12 Tesla and temperatures down to 0.3 K. Materials currently under particular investigations are novel superconductors, unusual magnetoresistive materials, low dimensional and frustrated magnetic systems and intermetallic rare earth compounds.
