Abstract
The cubic Laves Phase UAl2 is known to exhibit unusual magnetic and transport properties at low temperatures which have been explained by a narrow 5f-band in connection with strong spin fluctuations. Transverse and longitudinal μSR spectra taken between 300 K and 2 K show little variation in damping rate and muonic Knight shift. The fact that the weak damping seen in zero field can fully be decoupled by a longitudinal field of less than 10 mT shows that its origin lies in the interactions between the muon and the27Al nuclear moments, rather than in an influence of the uranium magnetic moments.
