摘要：

The authors have recently observed a giant electrocaloric effect (12 K in 25 V) in 350 nm sol-gel PbZr0.95Ti0.05O3 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 PbMg1/3Nb2/3O3-0.1 PbTiO3 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.
