Kurzfassung englisch:
On melt spun Nd60Fe30Al10 the temperature, frequency and DC-field dependence of the AC-susceptibility has been investigated. The temperature dependence of the AC-susceptibility shows an anomalous behavior which is characteristic of a spin-glass or cluster-like. Additionally the position of this anomaly depends strongly on the annealing temperature of the alloy. Similar to the time dependence of the coercivity, the magnetic aftereffect is present for temperatures higher than 50 K. Mössbauer spectra show always two hyperfine field distributions: one which corresponds to small magnetic moments and another one, which is typicl of an amorphous magnetically ordered alloy.
