摘要：

In this paper, 0.93PMN-0.07PT thin film shows a giant electrocaloric effect at room temperature. At electric field shift of 723 kV/cm, the peak value of Delta S of 0.93PMN-0.07PT thin film is 13.05 J/K. kg. The largest change (12.24. degrees C in 15.18 V, i.e. 0.8 K/V) at T-C = 27 degrees C is more than the previous results obtained in giant electrocaloric PbZr0.95Ti0.05O3 films near the ferroelectric Curie temperature of 222 degrees C (12 K in 25 V, i.e. 0.48 K/V) [A. S. Mischenko, et. al. Science 311, 1270 (2006)]. Copyright 2013 Author(s). This article is distributed under a Creative Commons Attribution 3.0 Unported License.
