摘要：

We present muon spin relaxation measurements performed at the Rutherford Appleton Laboratory in metallic compounds well known to be characterized by small magnetic moments, if any. Thanks to the low background we are able to unambiguously differentiate the various functions for the decay of the muon depolarisation. This allows one to distinguish between dynamical (YbB12) and static (URu2Si2, CeRu2) magnetic correlations, and between a disordered magnet (CeRu2) and a magnet with a limited correlation length (URu2Si2) Surprisingly, in UPt3 we do not find any signature of electronic magnetic correlations.
