Abstract

The La_0.2235 Pr_0.2235 Nd_0.2235 Sr_0.33 MnO₃ (LPNSM) ceramic has been obtained from oxides by sintering in air. The electrical properties of this material have been studied using ac impedance spectroscopy technique over a wide range of temperatures and frequency. Furthermore, a detailed analysis of the impedance spectrum suggested that the electrical properties of the material are strongly temperature dependent and have a good correlation with the sample microstructure in different temperature ranges.
