Study of the electrical and dielectric measurements of a rare-earth doped perovskite La0.6Nd0.1Sr0.3Mn0.7Ti0.3O3

Abstract : Electrical and dielectric properties of a polycrystalline La0.6Nd0.1Sr0.3Mn0.7Ti0.3O3 sample prepared by standard solid state reaction technique are presented. FTIR studies have showed the vibration of (Mn/Ti)O6 octahedra. The complex impedance is investigated in a temperature range 120–340 K and in frequency range 40 Hz–10 MHz. The impedance spectra have indicated that the electrical properties are strongly dependent on temperature and frequency, showing a good correlation with the sample microstructure. Ac conductivity is found to obey Jonscher power law. The value of activation energy estimated from the conductivity analysis is slightly higher than that deduced from relaxation analysis. © 2016, Indian Association for the Cultivation of Science.
