A strain-driven thermotropic phase boundary in BaTiO3 at room temperature by cycling compression

In BaTiO3 single crystals, we observed a strain-driven phase transition from the tetragonal phase to the tetragonal-orthorhombic phase boundary which can be introduced by slow cycling compressions (a loading of up to 0.5 GPa, strain rate of 10−4 s−1, and 100 cycles) at room temperature. Different fr...
