Electrocaloric effects across room temperature in multilayer capacitors

Nature, Published online: 06 May 2026; doi:10.1038/s41586-026-10492-w Multilayer capacitors comprising a solid solution of two electrocaloric materials PbSc0.5Ta0.5O3 and PbMg0.5W0.5O3 are shown to maintain high B-site order and latent heat without needing an energetically expensive anneal, enabling efficient refrigeration across room temperature.
