Room-Temperature Antiferroelectricity in Multiferroic Hexagonal Rare-Earth Ferrites

Jun Kasahara et al.

Summary: By preparing h-DyFeO3 films through epitaxial stabilization, the research team successfully expanded the AFE temperature range to 10-300K. The AFE phase originates from a nanomosaic structure comprising AFE P(3)over bar c1 - and ferroelectric P6(3)cm domains with small domain sizes of 1-10 nm, and weak ferromagnetism and magnetocapacitance behaviors are observed.

Decoding the relationship between the electrocaloric strength and phase structure in perovskite ferroelectrics towards high performance

Xiaowei Wei et al.

Summary: The electrocaloric effect can serve as an environmentally friendly cooling alternative to replace vapor-compression refrigeration. Research has shown that the phase structure significantly affects the electrocaloric properties, and by regulating the phase structure, optimized ΔT/ΔE can be obtained. Different phase structures result in varying changes in ΔT/ΔE and entropy coefficients, indicating distinct entropy change mechanisms.
