AbstractDielectric ceramics possess a unique competitive advantage in electronic systems due to their high-power density and excellent reliability. Na1/2Bi1/2TiO3-based ceramics, one type of extensively studied energy storage dielectric, however, often experience A-site element volatilization and Ti4+ reduction during high-temperature sintering.

Multiferroic materials consisting of multiple and mutually coupled order parameters including polarization can have an intriguing response to applied electric field, and give rise to the so-called cross-caloric effect, as the nondipolar degrees of freedom can contribute to the electrocaloric effect (ECE) via cross couplings to the electric dipoles.

AbstractPbZrO3 has been broadly considered as a prototypical antiferroelectric material for high-power energy storage. A recent theoretical study suggests that the ground state of PbZrO3 is threefold-modulated ferrielectric, which challenges the generally accepted antiferroelectric configuration. However, such a novel ferrielectric phase was predicted only to be accessible at low temperatures.
