Abstract

Transverse (up to 0.4 T) and zero field muSR was carried out between 300 K and 4.2 K in the spin fluctuator UAl-2 and the fairly localized antiferromagnet UAs. In the UAl-2 the fluctuation of uranium moments is too fast at any temperature to be seen by muSR. In UAs quite different muSR spectra were found for the two antiferromagnetically ordered spin structures. In zero field, the type I (single k) phase showed no mu**>f5<&< spin rotation, while in the type IA (double k) structure an overlay of three subspectra was observed, two of which have temperature dependent rotation frequencies.
