The thermoelastic behaviour of the orientationally disordered ionic crystals in two dimensions

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

The anomalous temperature dependence of the elastic constantsc 11 andc 66 and the elastic instability temperatureT c are obtained in the two-dimensional microscopic model of the alkali cyanides crystals. It has been found, by means of the Michel and Naudts' theory of the translation rotation coupling, that the orientational disorder in the high-temperature phase leads to the critical softening of the shear elastic constantc 66.
