THE INTERACTION BETWEEN IRRADIATION-INDUCED DEFECTS AND MAGNETIC STRUCTURE
Hysteresis loop measurements were conducted on several commercial iron- nickel alloys during neutron irradiation at 90 deg K and ambient reactor temperature in both zero and saturating magnetic field. Isochronal annealing tests were also performed on the alloys after irradiation. The low temperature irradiation results indicated that magnetic properties were affected not by the point defects themselves but by their motion and eventual disposition. The radioinduced changes appeared similar to those observed in the alloys upon magnetic annealing, namely, short-range atomic ordering. However, in all cases the radioinduced changes were annealed out at temperatures below the usual ordering temperature. The recovery process appeared to be dependent upon the state of magnetization of the sample. (auth)
