“…Demand for powerful nanotechnology application is generating challenge among scientists and engineers to provide a stable and flexible system. In fact, more compounds have been suggested in this context and some perfection was achieved in various study fields by the perovskite system, for example, magneto-tunable photocurrent activity, Spin Hall-Magnetoresistive devices and electrocatalytic activity [1][2][3].…”

The perovskite sample La0.7Sr0.25Na0.05Mn0.7Ti0.3O3 (LSNM0.70T0.30) was produced via a solidstate route process. Impedance spectra of LSNM0.70T0.30 in the frequency interval [40Hz -1MHz] were studied at several temperatures [80K to 440 K]. The ac conductivity (ac) established that according to the Jonscher law. ac is described by Non-overlapping Small Polaron Tunneling model at low temperatures and Correlated Barrier Hopping model at high temperatures. From dc conductance analysis, conduction seems to be thermally activated, suggesting the existence of semiconductor process. Detailed investigation of impedance data revealed the non-Debye nature of the relaxation processes in the sample. In addition, Dielectric constant curves were applied to examine the relaxation dynamics of charge carriers. In fact, the Debye-like relaxation was performed on the basis of the polarization of spatial charges following Maxwell-Wagner model and Koop's phenomenological theory.
