Abstract

In this work, cobalt (Co) substituted magnesium Zinc nanocrystalline spinel ferrites having general formula Zn0.5CoxMg0.5-xFe2O4 (with x=0.1, 0.2, 0.3, 0.4, 0.5) were synthesized using chemical co-precipitation method. The Cobalt substituted magnesium was annealed at 450Cand characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and UV-visible spectroscopy. XRD analysis confirmed the formation of single phase spinel structure. The crystalline size was calculated using Scherer's formula and wasfound to be in 21.44 – 25.03 nm range. The lattice constant was found to decreases as substitution of Co is further increased. The decrease in lattice constant may attribute to the smallerionic radius of Co as compared to Zinc ion. The FTIR spectra for the samples measured in the range of 4000-400 cm-1exhibited symmetric stretching mode of vibration of tetrahedral and octahedral sites. The energy band gaps of the materials were calculated and were found to be in the range of 4.5 to 4.8eV.
