摘要：

Zero- and longitudinal-field muon spin relaxation measurements on a poly-crystal sample of a heavy-fermion superconductor CeCu2.1Si2 (TC=0.7K) have revealed an onset of static magnetic ordering below T approx. 0.8 K. The line shapes of the observed spectra in zero field indicate a wide distribution of static random local fields at muon sites, suggesting that the ordering is either spin glass or incommensurate spin-density-wave state. The observed width of the random local field at T=0.05K corresponds to a small averaged static moment of the order of 0.1μB per formula unit.
