Paper Abstract

This paper deals with the synthesis, characterization, and some applications of Mn-Zn ferrite nanoparticles. The Mn-Zn ferrite was prepared from metallic nitrates, iron citrate and citric acid with the co-precipitation method with different pH values and it was further used to synthesis Mn-Zn ferrite with polariser i.e. H2O2 (Hydrogen peroxide). The X-ray diffraction pattern shows the single phase spinel structure of the ferrites. The effect of pH and the oxidizing agent on the electrical properties of Mn-Zn ferrite was studied. The d.c. resistivity is improved with the pH value and further improved by the addition of H2O2 (Hydrogen peroxide), which acts as a strong oxidizing agent. The dielectric constant decreases with increasing pH value; at the same time the dielectric loss also decreases. Further the decrease in dielectric properties by addition of oxidizing agent are justified by inverse proportionality between resistivity and dielectric constant.
