M. Cutroni et al., FREQUENCY AND TEMPERATURE-DEPENDENCE OF AC CONDUCTIVITY OF VITREOUS SILVER PHOSPHATE ELECTROLYTES, Solid state ionics, 90(1-4), 1996, pp. 167-172
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 seve
ral relaxational contributions which are indistinct in the frequency d
omain. The low temperature experimental data are discussed and a propo
sed 'new universality' has been examined.
