The zero-field spin relaxation of positive muon is measured in spin-glasses AuFe and CuMn. A stochastic theory of muon spin relaxation in a random dilute spin system is formulated to deduce the correlation time of Fe (or Mn) moments. The observed correlation time increases rapidly from 10/sup -10/ sec (atTapprox.1.2T/sub g/) to 10/sup -5/ (at Tapprox.0.5T/sub g/), showing a sharp slowing down of spin fluctuation around T/sub g/.
