| Abstract: | The a.c. conductivity behaviour in the 20–300 K temperature range has been investigated for (Ag2S)x(AgPO3)1−x and (Ag2SO4)x(AgPO3)1−x glasses at various salt contents (x). The temperature dependence at selected frequencies in the radioand micro-wave region displays several relaxational contributions which are indistinct in the frequency domain. The low temperature experimental data are discussed and a proposed ‘new universality’ has been examined. |
