Abstract :
The results of AC electric conductivity measurements in Bi-Sr-Ca-Cu-O glasses are reported. Two components of the total conductivity were observed, and the activation energies of both processes was determined. Small polaron hopping between copper ions in a different valency state CuI-CuII is one process. We believe that the second conductivity component is CuI ion diffusion
