Abstract
Co0.3Zn0.7Fe2O4 ferrites were prepared by ceramic process and sintered 1250oC, 1300oC and 1350oC. The crystal structural, morphological and magnetic properties of ferrite were determined by X-ray diffractometry (XRD), scanning electron microscopy (SEM), and vibrating sample magnetometer (VSM) respectively. The result of samples show that cubic spinel ferrite and the crystallite size increases from 6.80 Å to 9.08 Å with the increase sintering temperature from 1250oC to 1350oC. The magnetization and cocercivity of samples were found to be ~22 emu/g and 29 Oe, respectively which independent of sintering temperature. The single crystal Co0.3Zn0.7Fe2O4 ferrite can be prepared at temperature 1350oC (rate 3oC/min) for 2 h. It was found that single crystal (311) plane.
