Abstract
We have recently observed a giant electrocaloric effect (12 K in 25 V) in 350 nm sol-gel Pb Zr0.95 Ti0.05 O3 films near the ferroelectric Curie temperature of 242oC. Here we 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)O3 - 0.1 PbTiO3 near the Curie temperature of 60oC. This reduction in operating temperature widens the potential for applications in novel cooling systems.
