Abstract
Solid solutions of Co1-xZnxFe2O4 ferrites (x = 0, 0.25, 0.5, 0.75, 1) were obtained using a modified sol-gel method. X-ray diffraction, Raman, and dielectric spectroscopy were used to study the effect of γ-irradiation at doses of 2.5, 5, and 10 kGy on changes in the structure and dynamics of the crystal lattice. It was found that the crystal lattice parameters of the samples remain unchanged under the influence of ionizing gamma radiation. According to Raman spectroscopy data, low irradiation doses promote the formation of radiation defects and the redistribution of cations among tetra- and octahedral positions in the spinel structure.
