ABSTRACT Nanocrystalline Nickel Zinc Ferrite particles (NixZn1- xFe2O4) with different composition were prepared by Citrate precursor method. The ferrite powders were characterized using X-ray diffraction (XRD), Vibrating sample magnetometer (VSM) and Mossbauer Spectroscopy tools. The maximum value of saturation magnetization was observed as 52.18 emu/g and Coercivity as 116.10 Oe in sample with x = 0.8. The Mossbauer spectroscopy results show two environments for iron nuclei. In contrast to bulk Ni-Zn ferrites, the lattice parameter in our samples has a tendency to nonlinearly decrease with increase in the proportion of Nickel. The range of average particle size is 7 nm to 18 nm as obtained from XRD line broadening.
