The alternating-current conductivity of these super-ionic glasses was measured under hydrostatic pressures, at various temperatures, in the radio-frequency range. The results revealed a monotonic decrease in conductivity with increasing pressures of up to 2kbar. At a given temperature, the onset of dispersive alternating-current conductivity depended upon the pressure.
