Аннотация:
We present the results of both direct measurements and modeling of the intensive electrocaloric effect DTAD in
ferroelectric triglycine sulfate under nonequilibrium thermal conditions and periodically varying electric field. In the narrow
region around the phase transition temperature TC, a visible difference was observed between the electrocaloric responses
at applying DTON and removal DTOFF of the constant electric field: |DTON| < |DTOFF| and |DTON| > |DTOFF| at T<TC and
T>TC, respectively. The variation of the frequency and profile of the periodic electric field at T<TC allowed one to obtain the
gradual decrease in the average temperature of the top of the sample compared to the bottom kept at the constant
temperature. At low frequency electric field, qualitative agreement was found between the time dependences of the
measured experimentally and calculated DT values.
