Abstract
The adverse variation of electrocaloric coefficient Δ<italic>T</italic>/Δ<italic>E versus</italic>the electric field at different phase structures was first noticed and reported, and it was employed to explore the optimization of both electrocaloric temperature change Δ<italic>T</italic>and Δ<italic>T</italic>/Δ<italic>E.</italic>
