Abstract

(Pb_0.97La_0.02)(Zr_xSn_0.94-xTi_0.06)O₃ (PLZST) antiferroelectric ceramics with x = 0.75-0.90 have been fabricated and found to be a novel electrocaloric material system with a giant negative electrocaloric effect (ΔT = -11.5 K) and a large electrocaloric strength (|ΔT/ΔE| = 0.105 K cm kV^-1) near room temperature. Additionally, the PLZST antiferroelectric ceramic also exhibits a large positive electrocaloric effect around the Curie temperature. The giant negative effect and the coexistence of both positive and negative electrocaloric effects in one material indicate a promising possibility to develop mid- to large-scale solid-state cooling devices with high efficiency.
