Abstract

The cluster glass Y(Fe x Al1−x )2,x=0.75, 0.65 and 0.40 was investigated in external fields between 4.5 and 13.5 T at temperatures above the freezing temperatureT f. To explain the relaxation effects, which dominate the magnetic behaviour up toT∼7·T f, a model is proposed, where magnetic clusters are formed stochastically and decay after a mean life time.
