The AC electrical properties of the glasses of compositions (PbO)100-x(Fe2O3)x, where x=5-30 mol% are reported in the temperature range 90-300 K and in the frequency range 0.4-100 kHz. The experimental data have been analysed in the light of theoretical models proposed for AC conduction in semiconducting glasses. Analysis shows that classical hopping of electrons over a barrier can adequately explain the temperature and frequency dependence of the AC conductivity and its frequency exponent. Reasonable values of the relaxation time and barrier height have been obtained from the fits of the experimental results to the model.
