Abstract
Zero- and longitudinal-field muon-spin-relaxation measurements on a heavy-fermion system CeCu2.1Si2 have revealed an onset of static magnetic ordering below TM∼0.8 K, which coexists with superconductivity below TC=0.7 K. The line shapes of the observed muon spin depolarization functions suggest an ordering in either the spin-glass or incommensurate spin-density-wave states, with a small averaged static moment of the order of 0.1μB per formula unit at T→0.
