Investigations on Optical and Electrical Conductivity of Ba/Ni/Zn/Fe16O27 Ferrite Nanoparticles

Abstract

The Barium w-type ferrite powder with the composition formula (BaNi2-xZnxFe16O27, with x=0.0, 0.4, 0.8, 1.2, 1.6, and 2) were synthesized by using the ceramic method. The X-ray analysis confirms the formation of a single-phase w-type hexagonal structure. The lattice constant increases slightly with increasing the zinc concentration. UV-VIS analysis of the sample was carried out. The band gaps can be obtained at different concentrations from the zinc and have band gaps in the semiconducting region. The optical constants of absorption coefficient, extinction coefficient, refractive index, and reflection showed systematic variation with Zn concentration. The optical and electrical conductivity ware be observed increases with photon energy, and the conductivity peak of the samples increases with a decrease in Zn content. The electric susceptibility decreases with an increase in the Zn concentration.
