The effect of fe and mn substitution on structural and electrical properties of LaCoO3 nanoparticles

Abstract

Pure and Fe, Mn doped LaCoO3 nanoparticles are primed by sol gel ignition method, and their electrical properties are studied. All the materials were characterized to study the structure and morphology. The chemical composition of the samples was analysed by EDAX analysis revealing that La, Co, O (Mn, Fe) compounds were present. Electrical properties were identified in impedance analysis and the conductivity of the materials was calculated. And it is found that Fe doped LaCoO3 possesses higher conductivity than all others.
