Zero- and longitudinal-field muon-spin-relaxation measurements on a heavy-fermion system CeCu/sub 2.1/Si/sub 2/ have revealed an onset of static magnetic ordering below T/sub M/approx.0.8 K, which coexists with superconductivity below T/sub C/ = 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 0.1..mu../sub B/ per formula unit at T..-->..0.
