Abstract
The present studies reports the synthesis of Zinc ferrite (ZnFe2O4) composite with cobaltic oxide (Co3O4) by chemical co precipitation method. Sintering of the as synthesized sample has been done in a conventional furnace having heating rate of 5 °C per minute at three different sintering temperatures namely 600 °C, 750 °C, 900 °C. X-ray Diffraction (XRD) analysis shows the presence of cubic spinel ferrites with increasing crystallite size with the increase of sintering temperature. FTIR reveals the presence of absorption band due to metal oxygen vibrations. VSM measurement reveals the magnetic properties of ZnFe2O4 composite enhances thereby obtaining the maximum values of magnetization, coercivity and retentivity at 900 °C. The values of magnetization at 15.5 kOe, coercivity and retentivity observed were 19.355 emu/gm, 14.507 Oe and 0.24802 emu/gm respectively for the composite sintered at 900 °C. The understanding regarding the variation in the magnetization is discussed.
