Notes:
The organization of the conducting ions is studied by means of X-ray diffuse scattering as a function of temperature. While at high temperature (750°K) the conducting ions are organized in a two-dimensional 'quasi-liquid' structure perpendicular to the c axis, at low temperature (77°K) they form micro-domains corresponding to a two-dimensional superstructure with a lattice constant of a√3 = 9.68 Å (a = lattice constant of β alumina). The size of these micro-domains, which is about 50 Å at 77 °K, decreases progressively with increasing temperature.
