摘要
Transverse spin freezing in a-Fe92Zr8 has been studied using longitudinal field muon spin relaxation in fields of up to 5.5 T. The fluctuations associated with freezing of the transverse spin components are confirmed as a robust signature of T-xy. A 1/B dependence for T-xy(B) is observed, in qualitative disagreement with all current theoretical descriptions of the transition.
