Investigation of the electrocaloric effect in BaTiO3 multilayers by pASC calorimetry

The electrocaloric heat production in $$\hbox {BaTiO}_3$$ -based multilayer ceramic capacitors with Y5V specification was measured in a direct way by means of an adiabatic calorimeter setup. Applying an electric field of 30 $$\hbox {MV}\,\hbox {m}^{-1}$$ is found to result in a heat release of 0.94 $$\hbox {J}\,\hbox {g}^{-1}$$ and an electrocaloric temperature change of 0.46 K, in good agreement with direct results in previous studies.
