摘要：Herein the preparation of ferrite materials by using chemical reactions such as SOL-GEL AutoCombustion Technique is explained and importance of Nanocrystalline spinel ferrite material. Structuralcharacterization of the annealed samples at 400˚C for 4 hours was done by using X-ray diffraction method (XRD). Thesingle phase formation of NiCuCoFe2O4 was confirmed by X-ray diffraction analysis. The Fourier transfor Infra RedSpectra (FT-IR) confirmed that the synthesized material is ferrite. XRD revealed that the average crystalline particlesize which was calculated by using Scherer method is between 22 to 32 nm. The lattice constant is also calculated. Thepellets are made from ferrite powder by using polyvinyl alcohol (PVA) as binder. The data obtained from LCR-Q meteris used for calculating Dielectric loss tangent (tan δ), Dielectric constant (έ) and AC Conductivity in the frequencyrange of 100Hz to 5MHz at room temperature. The effect on Particle size is observed due to doping of Ni2+ , Co2+ andCu2+ in CuCo, NiCu and CoNi respectively .The correlation ship between the Particle size, lattice constant and ACConductivity is explained.
