Abstract
The authors have recently observed a giant electrocaloric effect (12 K in 25 V) in 350 nm sol-gel PbZr(0.95)Ti(0.05)O(3) films near the ferroelectric Curie temperature of 242 degrees C. Here the authors demonstrate a giant electrocaloric effect (5 K in 25 V) in 260 nm sol-gel films of the relaxor ferroelectric 0.9 PbMg(1/3)Nb(2/3)O(3)-0.1 PbTiO(3) near the Curie temperature of 60 degrees C. This reduction in operating temperature widens the potential for applications in cooling systems. (c) 2006 American Institute of Physics. (DOI:10.1063/1.2405889)
