摘要：

The thermomagnetic curve and magnetic aftereffect in a melt-spun Nd12.4Fe81.6B6.0 were measured above room temperature. The change in magnetization DELTA-M with time, t, was described by the relation DELTA-M = const + S log(t). A contour map of the coefficient S was obtained as function of temperature and magnetic field. The variations can be interpreted by the thermal fluctuation aftereffect.
