|Title||AC and Dielectric Properties of Polycrystalline Zn – Ni Spinel Ferrites Prepared by Double Sintering Technique|
The mixed polycrystalline ferrites , were obtained using the standard double sintering technique of mixing high purity of metal oxides , and for different concentration of Ni content. Double probe electrode method was used to measure the AC electrical conductivity ( ), real dielectric constant ( ε'), the imaginary dielectric constant ( ε''), the complex dielectric constant ( ε*) and the dielectric loss tangent (tan δ) over a variable angular frequency in range of at room temperature. for the given samples shows a continuous increasing with the increasing of the applied angular frequency. The results obtained from the dielectric parameter for all the samples decreases with increasing of frequency, which indicated to normal spinel ferrite behavior. The variation of AC and dielectric parameters were explained on the basis of electronic exchange between or . The experimental results reveal that the electrical and dielectric properties, which can be dramatically, changed by substitution of the Ni content in spinel ferrite. These improved properties of the mixed Zn-Ni spinel ferrite suggest uses as a soft ferrite material, which is proving an interesting material for technological and scientific applications.
