Abstract

The precession of positive muons in AIMnx samples with x ranging from 5 to 1300 ppm was studied. All the samples show a maximum in the µSR linewidth around 17 K, with a linewidth depending on the Mn concentration. In samples of AIMgx, AILix and AIAgx with x = 40 – 120 ppm the maximum occurs at different temperatures 17 – 45 K. This suggests that the muons are trapped in a strain field characteristic for each kind of impurity atom.
