The pure spinel phase of Ni0.45Co0.2Zn0.35F2O4 was prepared by coprecipitation method and ceramic method. The nanocomposite [(NCZF)1–x(Na(ac.ac))x] (x = 0%, 20%, 40%, 60%, 80%, 100%) was prepared by mixing two phases, Ni0.45Co0.2Zn0.35F2O4 with coprecipitation method [NCZF] and sodium acetylacetonate [Na(ac.ac)]. The TEM photographs of the as prepared ferrite samples by coprecipitation method at different ratios of Na(ac.ac) show that the crystalline cubic nanoparticles diameter were ranged from 26 - 36 nm and the particle size of Na(ac.ac) is greater than NCZF. The same behavior has also confirmed by XRD pat-terns indicating polycrystalline nature of prepared sample. The comparison between the SEM micrographs for NCZF nanoparticles prepared by a) ceramic method and b) co-precipitation method was done to show the effect of preparation condition on the microstructure. IR analysis confirms the composites formation.
