The first step in studying the influence of gamma radiation on magnetic properties of CoFe_2O_4 nano-particles
Document info: Pages 7, Figures 5.
The influence of radiation on magnetic material has been investigated in some researches and the results proved that the magnetic properties of hard magnetic were unchangeable under radiation effect [1,2,3]. Our works were aimed at studying the influence of gamma radiation on the nano-size magnetic materials. The gamma radiation with 1332 keV and 1174 keV energy was emitted on CoFe_2O_4 nano-particles with various doses. The comparison of properties of the materials before and after emitting was analyzed by hysteresis loop VSM. The change of magnetic properties of CoFe_2O_4 nano-particles after radiating appeared.
