摘要：

We report on zero-, transverse- and longitudinal-field mu+SR studies on a high-quality single crystal of CeRu2Si2. The development of some sort of static magnetism (Ce-moment congruent-to 0.001mu(B) below 1.5 K is observed in the zero-field relaxation rate. Measurements in longitudinal fields demonstrate the static character of this magnetism and reveal in addition the presence of dynamic 4f spin fluctuations (also observed in the transverse-field spectra) which coexist with the static magnetism below 1.5 K.
