Abstract
Frequency domain measurements on Na2B4O7 and Na(2)B(4)O7 (95%)-V2O5(5%) glass systems have been carried out in the frequency range 10(-2) to 10(4) Hz and temperature range 300 to 450 K. The complex capacitance has shown fractional power law dependences on frequency which obey the generalized Maxwell-Wagner relationships. The activation energy is found to increase with an increase in V2O5 composition.
