Description

Transverse (up to 0.4 T) and zero field μSR was carried out between 300 and 4.2 K in the spin fluctuator UAl2 and the fairly localized antiferromagnet UAs. In UAl2 the fluctuation of uranium moments is too fast at any temperature to be seen by μSR. In UAs quite different μSR spectra were found for the two antiferromagnetically ordered spin structures. In zero field, the type I (single k) phase showed no μ+ spin rotation, while in the type IA (double k) structure on overlay of three subspectra was observed, two of which have temperature dependent rotation frequencies.
