Bulk resistance in (in left side, black solid sphere) and capacitance in nF (in right side, blue solid star) of the equivalent circuit of slow cooled PbNb2O6 with rhombohedral phase, plotted against temperature, . Here, and have been calculated from Nyquist diagram of and in 20 Hz to 5.5 MHz range and the corresponding time constant , related to the dielectric relaxation time.
