Research Interests

Materials Science

Currently, our research focuses on the synthesis and characterization of novel electronic and magnetic materials. Polycrystalline and single crystal samples are made from a variety of synthesis techniques, including: solid-state reactions, arc melting, chemical vapor transport, RF-induction melting, and metallic fluxes. A material's structure and phase purity are then determined by X-ray diffraction and microprobe analysis. Magnetic, electronic, and thermal properties are measured over a broad temperature range from above room temperature to below that of liquid helium. The types of materials we investigate fall under the broad category of strongly correlated electron systems, and include: Kondo insulators, low-carrier density magnets, intermetallic superconductors, and thermoelectrics.
