AbstractThe compositional manipulation of the multiphase coexistence in relaxor-ferroelectrics has been reported to be an effective approach to generate the giant electrocaloric effect. In this work, we systemically investigate the temperature-dependent electrocaloric effect in BaZr0.18Ti0.82O3-BaSn0.11Ti0.89O3 relaxors, where Zr and Sn are introduced into BaTiO3 to develop the multiphase coexistence at the ferroelectric-paraelectric transition. Through the direct measurement by the heat flux sensor, a large temperature change around 4 K under an electric field of 10 MV m(-1), combined with a broad temperature span (20 degrees C-60 degrees C), has been observed. For comparison, the electrocaloric properties are also indirectly deduced based on Maxwell equations and Landau-Ginzburg-Devonshire phenomenological theory, and the validity of the indirect methods in this relaxor-ferroelectric system has been discussed. This work would shed light on developing giant electrocaloric materials with a wide operating temperature range. Published under license by AIP Publishing.
