Abstract

Electric relaxation in ion conducting materials is still interesting due to its deviation from the ideal resistor capacitor behavior due to correlated hopping ion dynamics. In the present study we have used an unusual complex anomalous relaxation function which has a functional form in both frequency and time domain to understand the correlated motion of ions. Ion conducting Na4Nb(1-x)Cd2.5xP3O12 (x=0.1, 0.25, 0.5) glass are prepared and its ac impedance spectroscopic data are investigated for ion dynamics and electric relaxation have studied in terms of fast and slow process.
