Description
We report on a μSR study of U1-xThxPt3 (0=<x=<0.05) conducted to investigate the onset of ''large-moment antiferromagnetism'' (LMAF). At low Th content (x=<0.002) magnetic ordering on the time scale of the μSR experiment (10-8s) is not detected. For x=0.005 a weak magnetic signal appears below T=2K, while for 0.006=<x=<0.05, spontaneous oscillations in the μSR spectra signal the presence of the LMAF phase. Analysis of the μSR spectra with a three-component depolarization function reveals that the magnetic phase transition is quite broad. The broadening may be the effect of disorder on the fluctuation spectrum of the small-moment antiferromagnetic state reported for UPt3 below TN∼6K
