Аннотация: We present the results of both direct measurements and modeling of the intensive electrocaloric effect T-AD in ferroelectric triglycine sulfate under nonequilibrium thermal conditions and periodically varying electric field. In the narrow region around the phase transition temperature T-C, a visible difference was observed between Показать полностьюthe electrocaloric responses at applying T-ON and removal T-OFF of the constant electric field: |T-ON| |T-OFF| at T<t-c and="" t="">T-C, respectively.
