Frequency Dependence of AC Conductivity in Iron Phosphate Glasses

Frequency Dependence of AC Conductivity in Iron Phosphate Glasses

Based on Jonscher power law, frequency dependence of ac conductivity of 40Fe2O3–60P2O5 glasses were investigated in a relatively high temperature range. Results indicated the power law exponent first decreases with increasing temperature, reached a minimum at a certain temperature and then in- creas...

Zusammenfassung:Based on Jonscher power law, frequency dependence of ac conductivity of 40Fe2O3–60P2O5 glasses were investigated in a relatively high temperature range. Results indicated the power law exponent first decreases with increasing temperature, reached a minimum at a certain temperature and then in- creases again. Preliminary theoretical explanations and predictions for this phenomenon were presented.
