Condensed Matter ExperimentResearch Interests
Research interests include: Highly correlated f-electron metallic compounds made in our own laboratory involving either Ce or depleted U are investigated using specific heat, susceptibility, and resistivity down to 3He temperatures and in fields up to 16 T (in-house) / 45 T (NHMFL Tallahassee) / 60 T (Los Alamos long pulse NHMFL facility). Advances in our understanding of the unusual magnetic and superconducting properties of these materials is aided with the further help of active outside collaborations with University of Goettingen, Germany, Los Alamos National Laboratory, and recently with Seoul National University.Selected Publications
