We have reported the variation of dc conductivity with annealing time and the
imaginary part of modulus spectra of Ag+ ions in the frequency range 40 Hz-110 MHz of the
heat-treated sample 0.70AgI-0.15Ag2O-0.015Cu2O-0.135MoO3 at room temperature. We
have observed that the variation of dc conductivity with annealing time shows a linear
relationship, which indicates that ion conduction process is independent of the annealing time.
We have also observed that the variation of relaxation time with annealing time follows a
proposed power law from which the fractal dimensionality of the ion motion is predicted. The
stretched exponent, obtained from the imaginary part of modulus spectra is found to vary with
the annealing time which indicates the change in structure during annealing.
