    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 100oc to 1000oc caused increasing of saturation magnetization (ms) from 25 to 73 emu/g and mean crystallite size from 11 nm to 35 nm.
