Abstract

In this work, we report the influence of Co-doping on the electronic band structure, dielectric and magnetic properties of La0.1Bi0.9Fe1−xCoxO3 ceramics. X-ray photoelectron spectroscopy investigation shows that Co dopant can shift the valence band spectrum and core-level lines of constituent elements towards higher bind energy regions simultaneously increase the concentration of oxygen vacancies in ceramics. The effects of dopant are discussed with focus given to the Co-doping induced enhancement of electrical conductivity and resistive switching phenomena.
