Abstract
Initial ac susceptibility χ was examined in the temperature range from 4.2 K to Curie temperatures for polycrystalline Fe100−xNix (20≤x≤50) alloys. The reentrant spin glass is found in x=30–45 alloys. The dependence of the freezing temperature Tg on the intensity of driving magnetic field (ac: 0–0.26 Oe; dc: 0–10 Oe) and on the frequency (140–9200 Hz) was studied for the Fe65Ni35 alloy. A strong magnetic relaxation is observed below Tg. These results are discussed based on the cluster model.This publication has 17 references indexed in Scilit:
