Structural, Optical and Dielectric Properties of (CoxCu0.15 Zn0.85-x Fe2O4) Ferrite Synthesized by Auto Combustion Method

Alaa F. Sulaiman

Abstract: The structural, optical and dielectric properties were studied of cobalt ferrite ( CoxCu0.15Zn0.85-x Fe2O4) where x =0.15, 0.3, 0.45 and 0.6 synthesized by sol-gel/auto combustion method. All samples were investigated by X-ray diffraction (XRD), UVVisible, LCR meter and scanning electron microscopy (SEM). The results appeared the average grain size was found in the range of ( 24 nm 37 nm) and found that, the lattice parameter decreased from 8.412 to 8.377 with increasing Co+2 ions content. The dielectric measurements as dielectric constant and dielectric loss for the prepared samples are studied as a function of frequency and cobalt content. The optical measurements are carried out in the wave length range between (200nm 1000nm), the results showed the transmittance and absorbency spectrum depend on the Co content for all samples.
