Neutron scattering from the superionic glasses, (AgI)x(AgPO3)1−x, through the glass transition

We have performed neutron scattering measurements to study the temperature dependence of the scattering from the superionic glasses (AgI)x(AgPO3)1−x with x=0.0, 0.3, 0.5 and 0.7 between room temperature and a temperature well above the calorimetric glass transition temperature, Tg. The temperature dependence of the positions of the glass/liquid diffraction peaks is featureless except in the pure AgPO3 glass where we observe a change in the …
