Structural, morphological, magnetic and electrical properties of LaNa □ MnO (0.00 ≤ ≤ 0.15) manganites.

LaNa □ MnO (0.00 ≤ ≤ 0.15) manganites were successfully synthesized using the solid-state route.

Understanding the transport properties of perovskite compounds as a function of temperature, frequency and DC-bias voltage using experimental measurements and appropriate theoretical models.

The present paper provides interesting measurements and methodologies to investigate the key factors controlling the electrical response of perovskite systems. The studied system was successfully prepared using a solid-state route. The chemical analysis and the X-ray diffraction results confirm the formation of the desired perovskite phase.

Effect of Sintering Temperature and Polarization on the Dielectric and Electrical Properties of LaSrMnO Manganite in Alternating Current.

The electrical characterization ofa LaSrMnO compound sintered at 800, 1000 and 1200 °C was investigated by means of the impedance-spectroscopy technique. As the results, the experimental conductivity spectra were explained in terms of the power law. The AC-conductivity study reveals the contributions of different conduction mechanisms.
