Muon studies of heavy fermions
Recent muon spin relaxation ({mu}SR) studies have been particularly effective in revealing important properties of the unusual magnetism and superconductivity found in heavy fermion (HF) systems. In this paper {mu}SR experiments elucidating the symmetry of superconducting order parameter in UPt{sub 3} and UBe{sub 13} doped with thorium and reviewed. Also discussed is the correlation between the enhanced superconducting specific heat jump and the reduced Kondo temperature in B-doped UBe{sub 13}, indicating possible direct experimental evidence for a magnetic pairing mechanism in HF superconductors. 23 refs., 3 figs.
