Abstract
A series of the ferrite system Co0.6Zn0.4MnxFe2-xO4 with (x = 0.7, 0.8, 0.9 and 1) were prepared by general ceramic method. The X-ray diffraction patterns confirmed the formation of the cubic single phase structure. The lattice parameter and the crystal size increased after irradiation which was attributed to the formation of ferrous ions of larger radius than that of ferrous ions in unirradiated samples. A small shift was observed in the diffraction peak position. This indicated the slight distortion of the cubic structure. The diffusion coefficient of electrons was found to be increased for the irradiated samples. The concentration of electrons was estimated and was found to be increased after γ-irradiation.
