Description
Summary:Order-disorder mechanism is a part of phase transition nature in the ABO 3 perovskites. It is related with the existence of polar regions, which dynamics in the electric field determines the dielectric response near T c . Temperature dependence of mechanical strain connected with polarisation change in the paraelectric phase has been investigated for the BaTiO 3 and PbZrO 3 single crystals. Existence of polar regions influences the electrostrictive properties and induces the piezoelectric effect in the paraelectric phase. A non-linear temperature dependence of the electrostrictive coupling between the macroscopic strain and macroscopic polarisation has been found above T c .
