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