Abstract

We report on the analysis of mu SR and Mossbauer measurements of the metallic spin glasses Y(Fe0.65Al0.35)(2) and Y(Fe0.4Al0.6)(2) above the freezing temperature (T-f) in terms of a model taking into account a dynamical process of stochastic formation and decay of magnetically correlated regions. By this model a comparison of the autocorrelation function determined by the two different measuring techniques is possible. For the temperature dependence of the autocorrelation time we find fair agreement between both experiments for T > 2T(f). (C) 2001 Elsevier Science B.V. All rights reserved.
