Abstract
The electrocaloric effect (ECE) in (1− x )BaZr 0.18 Ti 0.82 O 3 –( x )BaSn 0.11 Ti 0.89 O 3 (BZT18–BST11, 0.1≤ x ≤0.5) ceramics is investigated near room temperature using a calorimetry method. The ceramics exhibit relaxor-like ferroelectric characteristics and by merging phases, a large electrocaloric (EC) response is observed in the system. The largest entropy change is 4.8 Jkg −1 K −1 (along with a temperature change of 3.5 K), which is...
