  ABSTRACT: The pure spinel phase of Ni0.45Co0.2Zn0.35F2O4[NCZF] was prepared by co-precipitation method. The nanocomposite [(NCZF)1-x(Na(ac.ac))x] (x = 0%, 20%, 40%, 60%, 80%, 100%) was prepared by mixing two phases: ferrite phase and ferroelectric phase. The magnetic characters of compo-sites performed using vibrating sample magnitude (VSM) at room temper-ature with maximum applied field up to 2 kG. For smaller particle size 30.89 nm. The saturation magnetization Ms decreases linearly with increasing particle size. The effect of temperature on the electrical resistivity of the different composites samples was studied. It is noted that, the resistivity decreases with rising temperature to have a minimum value at ferroelectric transition temperature, above this value the resistivity increases. The dielectric constant increases with increasing temperature for all composites. The dielectric loss tan (δ) as a function of temperature sharply with temperature reached to maximum value at ferroelectric phase transition then decrease again.
