Perovskite Crystals: Unique Pseudo-Jahn–Teller Origin of Ferroelectricity, Multiferroicity, Permittivity, Flexoelectricity, and Polar Nanoregions

In a semi-review paper, we show that the local pseudo-Jahn–Teller effect (PJTE) in transition metal B ion center of ABO<sub>3</sub> perovskite crystals, notably BaTiO<sub>3</sub>, is the basis of all their main properties. The vibronic coupling between the ground and excited...
