Interaction between quantum paraelectricity and ferroelasticity in SrTiO3

The dielectric susceptibility of SrTiO3 is measured as a function of temperature between room temperature and 32 K. These data show an anomaly at approximately 105 K, which is associated with the cubic-tetragonal ferroelastic phase transition.
