Study of the La0.2235 Pr0.2235 Nd0.2235 Sr0.33 MnO3 ceramic by X ray diffraction and impedance spectroscopy

Abstract

The La0.2235 Pr0.2235 Nd0.2235 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. © Owned by the authors, published by EDP Sciences, 2012.
