摘要：

We describe recent progress of muon spin relaxation (muSR) studies in heavy-fermion (HF) and other strongly correlated electron systems. Measurements of the magnetic field penetration depth lambda in HF superconductors UPt3, URu2Si2, UPd2Al3 and U2PtC2 have revealed that these systems are characterized by large ratios T(c)/T(F) = 0.1-0.01 of T(c) vs Fermi temperature T(F) derived from lambda. This feature is common to high-T(c) cuprate and other exotic superconductors. Zero-field muSR studies of magnetic order have elucidated a cross-over from spin glass ordering to nonmagnetic ground states in the 'quadrupolar Kondo regime' of (Y1-xUx)Pd3, and also suggested a possibility of incommensurate spin-density-wave (SDW) ordering in UNi2Al3.
