摘要：

A method is proposed for studying the dynamics of the electrocaloric response of a ferroelectric capacitor to the pulsed action of the electric field, and the results of measurements are reported. The temperature of the capacitor was measured with the help of a ferromagnetic film resonator. The sensitivity of temperature measurements was ∼10−4 K/kHz. The recalculated temperature dependence of the resonance frequency showed that the ferroelectric ceramic sample was heated by 0.065 K and was cooled by 0.041 K relative to the thermostat temperature under the action of high-voltage pulses. The relaxation time of the electrocaloric effect of the 0.87PMN-0.13PT relaxor ferroelectric ceramic is 4.5 μs.
