چکیده انگلیسی
The sodium double perovskite NaLaMnMoO6 compound have been synthesized by the sol - gel method and characterized by X-ray diffraction (XRD) technique. The electrical conductivity and modulus characteristics of the system have been investigated in the temperature and the frequency range 332-373Â K and 200 Hz-5 MHz respectively by means of impedance spectroscopy. The ac and dc conductivities were studied to explore the mechanism of conduction. Dielectric data were analyzed using complex electrical modulus M* at various temperatures. The non-overlapping small polaron (NSPT) model can explain the temperature dependence of the frequency exponent. The electrical conduction in sodium double perovskite NaLaMnMoO6 compound is presumably caused by the motion of Na+ in the [â110] direction tunnel.
