Polycrystalline materials of Dy doped La1-xCaxMnO3 were prepared by Sol-Gel technique using citric acid as a chelating agent at 900°C. The compound was analyzed by powder X-ray diffraction technique and confirmed to be single phased orthorhombic perovskite structure with space group Pnma. From the dielectric and impedance studies confirmed the existence of dielectric relaxation and presence of space charge were observed from the dielectric constant and impedance plots respectively and confirms the existence of relaxation due to oxygen vacancy. Cole-cole plot confirms the presence of dielectric relaxation and grain contribution in the synthesized sample. © 2017 Author(s).
