Abstract

We report neutron-scattering measurements on the first sharp diffraction peak in the superionic conducting glass $(AgI)_{x} ({AgPO}_{3})_{1 - x}$ as a function of composition x from 0.0 to 0.7. The temperature variation is studied in detail between 300 K and 500 K, a range that spans the calorimetric glass transition. This peak reflects structure in the phosphate network with periodicity $d \approx 10 Å$ and correlation length $\approx 25 Å .$ The intensity of the first sharp diffraction peak shows an anomaly as a function of temperature at a temperature about 6–11 % higher than $T_{g}$ as measured calorimetrically. This is tentatively ascribed to the diffraction intensity reflecting the onset of $α$ relaxation, while the calorimetric data reflects the onset of $β$ relaxation.
