Abstract
The complex AC conductivity of the sol-gel-derived cobalt silicate gel -glasses is reported for the frequency range 10(2)-10(5) Hz and temper ature range 80-300 K. The experimental results were analysed in terms of theoretical models based on quantum tunnelling and classical hoppin g theories. It has been observed that classical hopping theory is the best model to explain the results for these glasses and that not all s ites participate in the AC hopping mechanism.
