Effect on and Correlation between Particle Size, X-ray densityand Dielectric Constant, of Nanocrystalline spinel Ferrite Material due to Doping of Ni 2+, Co2+ and Cu2+ in CuCo, NiCu and CoNi respectively prepared by Sol Gel Auto Combustion Method.

Abstract

Herein the preparation of ferrite materials by using chemical reactions such as SOL-GEL Auto Combustion Technique is explained and important physical and Dielectric properties of Nanocrystalline spinel ferrite material.Structural characterization of the annealed samples at400?C for 4 hours was done by using X-ray diffraction method (XRD). The single phase formation of NiCuCoFe2O4 was confirmed by X-ray diffraction analysis. The Fourier transfor InfraredRed Spectra (FT-IR) confirmed that the synthesized material is crystalline spinel ferrite. XRD revealed that the average crystalline particle size which was calculated by using Bragg’s lawand Scherer method is around 29 nm. The X-ray density is also calculated. The pellets are made from ferrite powder by using polyvinyl alcohol (PVA)as binder and by using LCR-Q meter, the Dielectric constant is calculated in the frequency range of 100Hz to5MHzat room temperature. The effect on Particle size,X-Ray Density and Dielectric Constant is observed due to doping of Ni2+ , Co2+ andCu2+ inCuCo, NiCu and CoNi respectively .The correlation ship between the Particle size, X-ray density and Dielectric Constant is discussed.
