Room temperature giant electrocaloric properties of relaxor ferroelectric 0.93PMN-0.07PT thin film
Source abstract
Abstract
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 ΔS of 0.93PMN-0.07PT thin film is 13.05 J/K.kg. The largest change (12.24 °C in 15.18 V, i.e. 0.8 K/V) at TC = 27 °C is more than the previous results obtained in giant electrocaloric PbZr0.95Ti0.05O3 films near the ferroelectric Curie temperature of 222°C (12 K in 25 V, i.e. 0.48 K/V) [A.S. Mischenko, et.al. Science 311, 1270 (2006)].
