Abstract:
Three series of nanocrystalline Ni0.7-xZn0.3MxFe2O4 ferrites (M ¼ Mn2þ, Co2þ, and Cu2þ; x ¼ 0.0, 0.1, 0.3, 0.5, and 0.7) have been synthesized using the citrate method. Several techniques have been used to investigate the influence of the different dopant ions and their doping levels on the structural and magnetic properties of the Ni–Zn ferrites. X-ray diffraction (XRD) analysis confirmed the creation of a single-phase spinel structure. The lattice parameter was found to increase with increasing Mn2þ and Co2þ ion concentrations, but was not altered by adding Cu2þ.
