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 Fe65Ni3 5 alloy. A strong magnetic relaxation is observed below T g. These results are discussed based on the cluster model.
