Abstract

Co_0.7Zn_0.3Fe₂O₄spinel ferrite was synthesized via a conventional solid-state reaction method and subsequently exposed to γ-irradiation doses up to 100 kGy. The effects of γ-irradiation on the structural, electronic, and magnetic properties were systematically investigated using X-ray diffraction (XRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), and neutron powder diffraction (NPD). The results demonstrate that the single-phase cubic spinel structure (space group Fd3m) remains stable throughout the investigated irradiation range, accompanied by a slight increase in crystallite size. XPS analysis confirms the stability of the Co²⁺, Zn²⁺, and Fe³⁺ oxidation states as well as the cation distribution between tetrahedral and octahedral sites upon irradiation. Furthermore, NPD results reveal that both the crystal and magnetic structures remain essentially unchanged under γ-irradiation. These findings indicate a high degree of structural and magnetic robustness in Co_0.7Zn_0.3Fe₂O₄ against irradiation-induced modifications.
