摘　　要：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.The pure spinel phase of Ni0.45Co0.2Zn0.35F2O4 was prepared by coprecipitation method and ceramic method.
