Room temperature giant electrocaloric properties of relaxor ferroelectric 0.93PMN-0.07PT thin film

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 resu...
