FIG. 1.

(Color online) Temperature dependences of and for ceramics measured at different frequencies: [(a) and (b)] and [(c) and (d)] . The insets of (b) and (d) display the typical microstructure of samples sintered at 1250 and , respectively. The inset of (c) shows the Arrhenius plots of the frequency dependence of the temperature for ceramics. Symbols are the experimental points and the solid line is the least-squares straight-line fit.

(Color online) ac conductivity and (b) combined and plots as a function of frequency at 273 and for ceramics sintered at . The arrows indicate anomaly frequency identified by and peaks. The inset of (a) shows the Arrhenius plots of the frequency and frequency vs . The inset of (b) shows the combined and plots at various applied voltages.
