Abstract:
We 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
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 PbMg1/3Nb2/3O3 – 0.1 PbTiO3 near the
Curie temperature of 60oC. This reduction in operating temperature widens the
potential for applications in novel cooling systems.
