Enhanced room-temperature electrocaloric performance by both multiphase coexistence and diffused phase transition in (Ba<sub>0.65</sub>Sr<sub>0.3</sub>Ca<sub>0.05</sub>)(Sn<sub><i>x</i></sub>Ti<sub>1−<i>x</i></sub>)O<sub>3</sub> ferroelectric ceramic
Multiphase coexistence and DPT are designed to enhance ECE. A very high Δ T of 1.79 K (indirect) and 2.19 K (direct) and large T span of 26 K (90% Δ T max ) and 45 K (80% Δ T max ) are obtained in the ceramics (Ba 0.65 Sr 0.3 Ca 0.05 )(Sn x Ti 1− x )O 3 for x = 0.02.
