Abstract

The temperature, frequency and DC-field dependence of the AC-susceptibility has been investigated on melt-spun Nd60Fe30Al10 . The temperature dependence of the AC-susceptibility shows an anomalous behavior, which depends strongly on the applied heat treatment and exhibits a cluster-like characteristic. Similar to the time dependence of the coercivity, a magnetic after-effect is present for temperatures higher than 50 K. 57 Fe Mössbauer spectra can be analyzed by two hyperfine field distributions pointing to two phases with quite different magnetic moments on the Fe sites.
