Abstract
In the present study, we have discussed about the synthesis of Ca0.9Dy0.1MnO3 by using citric acid as a chelating agent. Structural and morphological studies were carried out by using XRD, FT-IR, FE-SEM equipped with EDX for the synthesized material. Magnetic studies are carried out by VSM and confirmed the paramagnetic behavior. The electric properties like dielectric, impedance and conductivity is carried out at the frequency range of 50 Hz to 5 MHz for different temperatures. Impedances studied for the activation energy and the investigation of grain and grain boundary effects. The conductivity studies were explained on the basis of Jonscher's power law and the activation energy is calculated. Keywords: Sol–gel, Structural, Dielectric properties, Electrical properties, Impedance spectroscopy
