Mixed mobile ion effect on a.c. conductivity of boroarsenate glasses

摘要

In this article we report the study of mixed mobile ion effect (MMIE) in boroarsenate glasses. DSC and a.c. electrical conductivity studies have been carried out for e?‘￥MgOa€“(25a?’e?‘￥)Li₂Oa€“50B₂O₃a€“25As₂O₃ glasses. It is observed that strength of MMIE in a.c. conductivity is less pronounced with increase in temperature and frequency. The results were explained on the basis of structural model (SM) proposed by Swenson and his co-workers supporting molecular dynamic results.
