摘要：

The inherent dynamic properties of the ferromagnetic phase of a reentrant ferromagnet, (Fe0.20Ni0.80)(75)P16B6Al3, have been experimentally investigated by low field magnetic relaxation and ac susceptibility measurements. A prominent aging behavior and an apparent fatal fragility to temperature fluctuations imply that the ferromagnetic phase of the reentrant system has a chaotic nature similar to the spin glass phase, but in striking contrast to the robust nature of the regular ferromagnetic phase.
