Novel compounds with topological properties and magnetic order will be synthesized using a variety of methods, such as arc melting, Bridgman growth, optical float zone growth, as well as chemical transport and flux growth. The compounds will be characterized for the structural properties using diffraction methods, and their magnetic and electronic properties using the unique instrumentation accessible at the NHMFL. The postdoctoral scholar will get training in modern X-ray diffraction methods and will have access to the in-house developed systems, as well as the unique high field diffractometer located at the NHMFL. The high field diffractometer is unique in the world, with a DC field strength of 25 Tesla, surpassing any other system currently available. In addition, the postdoctoral scholar will characterize the thermoelectric properties of these novel compounds for energy conversion applications. The search for clean and renewable energy production methods relates directly to the discovery of novel materials and composites with novel structural and electronic properties. Thermoelectric materials hold tremendous promise for advances in both fundamental science and future applications, particularly for robust electricity generation in extreme and remote environments. The postdoctoral scholar will investigate the 4f- and 5f-electron systems to optimize the thermoelectric figure of merit of candidate materials through chemical substitution. This effort will contribute to the development of a new class of thermoelectric materials that could be used for low-temperature cooling applications.
