Abstract
The AC resistivities of some borate glasses containing either antimony oxide or arsenic oxide have been measured over a temperature range 125K to 400K. A sharp minimum in the resistivity values for all the compositions is observed around 280K. This behaviour is explained on the basis of a change in the ratio of A5+/A3+ (where A=Sb or As) as a function of temperature. The AC resistivity for temperatures below 280K is found to obey a ω−s law with 0.5 < s < 0.9. A bipolaronic conduction model is used to calculate the density of charged centres in these glasses.
