Abstract
The main purpose of this work was to study the electrical, structural and optical properties of Cd-doped Zn based soft ferrites. A series of nano-particles with composition Zn0.5Mn0.5- xCdxFe2O4 (x= 0.00, 0.01, 0.03, 0.05, 0.07, 0.09) prepared by the Co-precipitation route. After preparing, the samples sintered at temperature 900⁰C for 6 hours. Different characterization techniques like XRD (X-Ray-Diffraction), FTIR (Fourier-TransformInfrared-spectroscopy), UV-vis. and IV-characteristics were used to explore the effect of doping element (Cd) on the electrical, structural and optical properties of Nano-particles. XRD data confirmed the single phase of material with second phase of Fe2O3 and average crystalline size in range from 38.09-45.15 nm. The value of average lattice constant for the prepared material found in range from 8.4471 Å to 8.4763 Å. In FTIR data one prominent band is found in all sample and in some sample second band was found in range from 400- 4000cm-1. IV-observation revealed the dependence of DC-resistivity on temperature and the value for activation energy (∆𝐸𝐸) found in range from 0.1365 to 0.4332 eV/1000K. The UV-vis. analysis confirm the absorption peak for all samples at average wavelength 286 nm. At this wavelength absorption for all samples was in range from 2.8722-3.2956 (a.u). Cd concentration is responsible for the decrease of saturation magnetizations and losses. Due to suitable properties, these materials are useful in different fields like Recording-Media, high-frequency applications and many branches of electronic engineering etc.
