Abstract
This paper investigated the variation of structure and electrical properties of Lathanum Ferrite Oxide perovskite-based material. The A site of this perovskite dopped Mg, Sr, and Bi. The (La1-xAx)FeO3 samples were synthesized by sol gel method. For the present research study, the structure, of this material investigated by X-ray diffraction (XRD). For the surfaces and morphology structure this material, we are using Scanning Electron Microscopy (SEM), and then the electrical properties of this materials were investigated by using RLC Meter, the data plotted by using bode and nyquist plot. The optical band gap energy obtained by using Uv-vis spectroscopy and employed Kubelka-Munk method This lanthanum ferrite oxide-based perovskite has been reported as potential ionic conductivity materials at room temperature.
Keywords: Sol-gel, Perovskite, Structure, Band gap, ionic conductivity.
