Abstract
The authors have studied magnetic fluctuations in the paramagnetic phase of rare-earth-aluminium intermetallics of the type (RE)Al2 by the method of transverse-field muon spin rotation ( mu SR). In the case with strong 4f exchange they could observe a strong increase in the damping of the mu SR signal on approaching the Curie point Tc. One important contribution to the increased damping rate is the slowing down of magnetic fluctuations attributed to the formation of paramagnetic spin correlations which are observed to persist far above Tc. The crystallographic site for the mu + is discussed as well as the hyperfine field induced at this site due to interstitial electron polarisation.Keywords
