FIG. 5.

The dielectric loss spectra for two typical temperatures: (◆) and (●) with the fitted curves (solid lines) for a planar cell with brass electrodes for the cell thickness of for a frequency range of 100 Hz to 10 MHz. The dashed-line denotes fitting of the two relaxation processes and the dotted-line shows the conductivity for a temperature of .
