Because of their different time scales, Mössbauer spectroscopy and μ + SR give complementary information on spin glasses. We show that for standard spin glasses in zero field, the interpretation of longitudinal muon experiments in terms of a slowing down of large amplitude fluctuations, leads to characteristic times around TG which do not seem compatible with Mössbauer results.Du fait de leurs échelles de temps différentes, la spectroscopie Mössbauer et la précession des muons positifs fournissent des renseignements complémentaires sur les verres de spin. Dans les verres de spin classiques, des expériences « longitudinales » en champ nul sur les muons ont été interprétées en termes de ralentissement de fluctuations de grande amplitude; nou...
