Muon spin-relaxation measurements of the fluctuation modes in spin-glass AgMn

Conference ·
OSTI ID:5154870
Recently reported zero-field ..mu..SR measurements below the spin-glass transition temperature in AgMn (1.6 at. %) show a temperature dependent inhomogenous width. We discuss these data in terms of a model in which the local field undergoes limited-amplitude fluctuations. We find that both very slow (approx. 0.3 ..mu..s/sup -1/) and rapid (approx. 3000 ..mu..s/sup -1/) fluctuations are required.
