Iron pnictide superconductors (new materials as well as known compounds) AND highly correlated f-electron metallic compounds involving Yb, 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 starting in 2008 with Seoul National University.
