This paper reports the investigation on synthesis and magnetic characterization of Ni substituted Co 0.8Zn 0.2Fe 2O 4 nano-particles. The nano-particles of Co 0.8-xNi xZn 0.2Fe 2O 4 (x = 0.15,0.20, 0.35,0.50,0.65) were prepared by co-precipitation method. The X-ray diffraction analysis confirmed the formation of single-phase face centered cubic (fcc) spinal structure. The lattice parameter decreased as Ni concentration increased from x = 0 (a = 8.388 å) to x = 0.65 (a = 8.3612 å). The morphology of the particles examined through high-resolution TEM showed a well-isolated and less agglomerated homogeneous distribution of nano-particles which suggests that co-precipitation method is beneficial for magnetic nano-materials synthesis and their characterization. The influence of Ni on magnetic behavior (saturation magnetization and 4pM s) of Co 0.8-xNi xZn 0.2Fe 2O 4 nano-materials have been evaluated and discussed. © 2009 American Scientific Publishers.
