| Abstract: | We present the results of electrical resistivity measurements performed on 20Fe2O3803B2O3(1?x)PbOxAuOv] glasses, with AuOv=K2O, Ca, As2O3 and GeO2. For a given temperature the electrical conductivity is linearly dependent on the fraction of ferrous ions. The experimental data are well described by using a model involving small polarons. |
