Magnitude of Intrinsic Electrocaloric Effect in Pb(Zr_1-xTi_x)O₃at High Electric Fields

Abstract:

The structure transition and electrocaloric effect in PbZr_1-xTi_xO₃ with x=0.5 and 0.6 were MV/m can make the structural transition be a continuous one. In addition, when x =0.5 and 0.6 at the zero field, the first order structural transition occurs at T₀=665 and 691 K, respectively. The first order structural transition comes to the second one upon the strong electric field, which leads to lower the change of specific hea. The structural transition temperature is shifted at high temperature with increasing electric field. The maximum electrocaloric effect is present at about 200 K above their corresponding Curie temperatures.
