Synthesis and characterization of nickel zinc spinel ferrite synthesized by inverse co-precipitation method

Nickel zinc ferrite (NZFO) nanoparticles were synthesized by an inverse chemical co-precipitation method. Effects of synthesis conditions on the mean crystallite size, phase composition and morphology were investigated by X-ray diffraction analysis (XRD), scanning electron microscope (SEM) and vibrating sample magnetometer (VSM), respectively. XRD diffraction pattern exhibited representative diffraction peaks corresponding to as-dried powder and heat-treated powders. Regardless of heat-treatment, NZFO formed completely. SEM analysis studied morphology of nanoparticles with particle size of about 10 to 110 nm depended on the heat-treatment temperature. Results of VSM reveal the magnetic properties of produced compound in various heat-treatment temperature. It was shown that increasing the heat-treatment temperature from 100℃ to 1000℃ caused increasing of saturation magnetization (
