Abstract

Abstract Spinel type pure and Sr2+ doped zinc ferrite nanoparticles were prepared by glycine assisted combustion. The resultant nanoparticles were found to be highly crystalline with cubic crystal structure. The structure and the corresponding changes in the tetrahedral and octahedral bond stretching were investigated. The chemical elements and oxidation states of these nanoparticles were determined and the elemental compositions of synthesized nanoparticles established. It was observed that the optical band gap values increased from 2.43 eV to 2.49 eV as Sr2+ concentration increased. The morphology, chemical elements and composition of the prepared ferrites were examined. The magnetic behavior of these nanoferrites was studied and corresponding changes in the saturation magnetization, coercivity and remanent magnetization were analyzed.
