Ferroelectric materials based on BaTiO3 undergo a phase transition from a non-centrosymmetric polar ferroelectric phase to a cubic paraelectric centrosymmetric phase at Curie temperature (Tc) where spontaneous polarization is lost. However, recently it has been shown that cubic BaTiO3 phase exhibits breaking of nominal centric symmetry and exhibits polarization which was explained with the presence of polar nano-regions [1].
