Studies on the electrical and optical conductivity of Barium-Nickel ferrite nanoparticles doped with Zn

The ceramic process was used for making the Barium w-type ferrite powder, which has the composition formula BaNi2-xZnxFe16O27, where x=0.0, 0.4, 0.8, 1.2, 1.6, and 2. In essence, the single-phase w-type hexagonal structure development is confirmed by the X-ray investigation. The concentration of zinc increases along with a modest increase in the lattice constant. An analysis of the sample using UV-VIS was done. Zinc may be obtained at varying concentrations, and it is discovered that band gaps exist in the semiconducting zone. There was a consistent variation in the optical constants of absorption coefficient, extinction coefficient, refractive index, and reflection with Zn content. It can be seen that the optical and electrical conductivity rise with photoenergy, and that the samples' conductivity peak grows as the Zn content decreases. As the electric susceptibility rises, it falls . When the concentration of zinc increases, the electric susceptibility falls.
