Giant electrocaloric effect in high-polar-entropy perovskite oxides
Nature, Published online: 09 April 2025; doi:10.1038/s41586-025-08768-8Targeted multielement substitution of a lead-free relaxor ferroelectric perovskite distorts the lattice structure and induces strong polar disorder, leading to high-polar-entropy ferroelectric oxides with a high electrocaloric effect and long lifetime.
