Investigation of the electrocaloric effect in BaTiO3 multilayers by pASC calorimetry

Abstract

The electrocaloric heat production in BaTiO3 -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 MV m −1 is found to result in a heat release of 0.94 J g −1 and an electrocaloric temperature change of 0.46 K, in good agreement with direct results in previous studies.
