Giant Electrocaloric Response Over A Broad Temperature Range in Modified BaTiO₃ Ceramics

A giant electrocaloric effect (ECE) near room temperature is reported in a lead‐free bulk inorganic material. By tuning Ba(Zr x Ti 1–x )O 3 compositions which also exhibit relaxor ferroelectric response to near the invariant critical point, the Ba(Zr x Ti 1–x )O 3 bulk ceramics at x ∼ 0.2 exhibit a ...
