Electrocaloric effects in multilayer capacitors of stoichiometric lead scandium tantalate with varying B‑site cation order
… of stoichiometric lead scandium tantalate (PbSc0.5Ta0.5O3 or PST) have been shown to generate large thermal changes (known as electrocaloric, or EC, effects) in response to large changes in applied electric fields sustained without breakdown. These MLCs represent a solid‑state, more …

… near TC = 435 K, respectively. A cation-ordered PbSc0.5Ta0.5O3 ceramic showing a nominally first-order transition at 295 K was obtained. The Clausius-Clapeyron phase diagram is revealed via indirect measurements where |∆S| ∼ 3.25 J K−1 kg−1 and |∆T | ∼ 2 K, and direct measurements where |∆T | ∼ 2 …
