Relative permittivity and dielectric loss as a function of temperature, measured at 1 kHz under conditions of ZFC and ZFH. The inset shows the relative permittivity as a function of frequency and temperature. shifts to higher temperatures as frequency increases.
FH and FC loops at selected temperatures and 100 Hz.
Polarization as a function of temperature at selected electric fields and 100 Hz, as deduced from loops taken on FC and FH. Fits achieved by cubic-spline interpolation.
Predictions of electrocaloric temperature change in the 0.93PMN-0.07PT thin film, as a function of starting temperature, due to selected . Results were obtained using the indirect method separately for the FC and FH data in Fig. 3.
