Sg. Barsov et al., OBSERVATION OF THE DYNAMICS OF LOCAL MAGNETIC-FIELDS IN FRUSTRATED FERROMAGNETS BY THE MU-SR METHOD, JETP letters, 57(10), 1993, pp. 672-675
Slowly relaxing processes are shown to occur in the spin system of fru
strated ferromagnets in the group of structurally ordered (Mn1-xFex)Pt
3 alloys. These processes result from a dynamic crossover from a state
of ferromagnetism to asperomagnetism.
