Abstract
The temperature dependence of the magnetic aftereffect, ƊB/B, has been investigated between room temperature and Tc in two low-Tc FeNiSiB amorphous alloys. ƊB/B is observed to steadily decrease with T in a region near Tc, where the magnetic permeability stays almost constant. The results are analysed in terms of the structural model for the aftereffect.
