| Abstract: | Transverse-field muon spin roation (μSR) is studied in Cd1−xMnxTe, x=0.4 and 0.6 mixed crystals. A large temperature dependent frequency shift and a strong relaxation of the μSR-signal
are observed. In the vicinity of the spinglass transition, the relaxation rate becomes so large that the signal disappears.
The rate of Mn spin fluctuations causing the μ+-line narrowing at high temperatures is estimated to be of the order of 109 S−1. |
