On page 3165, Y. Liu and co‐workers demonstrate a giant negative electrocaloric effect (ECE) in antiferroelectric La‐doped Pb(ZrTi)O 3 thin films near room temperature. A possible mechanism of negative ECE in antiferroelectrics is proposed. One potential application for this negative ECE is to combine with conventional ECE to enhance further the cooling efficiency. The text description in the frontispiece for article adma201501100, on page 3164, was updated after original publication of the issue files due to an error during typesetting. This text correction only appeared in the issue files published online, and not in the printed issue.
