Frequency and Temperature-Dependence of AC Conductivity of Vitreous Silver Phosphate Electrolytes
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 radio- and 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.
