X-ray diffraction analysis, electrical resistivity measurements at room temperature, and differential thermal analysis (DTA) were carried out for γ-irradiated Ni 0.65 Zn 0.35 Cu xFe2−x O 4 spinel ferrite samples. It was found that the lattice parameter decreased, i.e. the theoretical density increased, while the electrical resistivity decreased. From the DTA analysis there is an endothermic peak at 100–130º C due to internal stress created by γ radiations as a result of lattice defects formation.
