The Influence of Gamma Radiation on Magnetic Properties of Fe₃O₄, Co_0.8Ni_0.2Fe₂O₄, Co_0.8Zn_0.2Fe₂O₄ Ferrite Magnetic Materials

Abstract:

The influence of radiation on magnetic material has been investigated in many researches which had proved that the magnetic properties of hard magnetic were unchangeable under radiation effect ^{[1],[2],[3],[4],[5],[6]}.In this work, we performed the study of the influence of gamma radiation on Fe₃O₄, Co_0.8Ni_0.2Fe₂O₄, Co_0.8Zn_0.2Fe₂O₄. The ⁶⁰Co gamma radiation was emitted on ferrite magnetic materials with doses 1000, 1500, 2000 kGy. Analyzing magnetic properties of the materials before and after emitting by Walker Automatic Hysteresisgraphs AMH 20-50. The change of (B-H) loop is insignificant. Our work agrees well with the result of ^[1][2][3][4].
