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), UV?Visible, 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. |
