Deformation studies on BaTiO3 single crystals

Abstract
Compressive deformation studies on BaTiO3 single crystals show that the crystals deform easily at room temperature because of the movement of twin boundaries which are the 90° domain walls. In the twin‐deformation region, the crystals exhibit time‐dependent deformation, which could be observed as stress relaxation. Some features of this deformation and relaxation behavior are reported.
