Abstract

A thermodynamic potential for Ba_1-_xSr_xTiO₃ solid solutions is developed, and the corresponding thermodynamic properties of Ba_1-_xSr_xTiO₃ single crystals are calculated. The predicted temperature-composition phase diagram from the thermodynamic potential agrees well with the experimental measurements. Based on this potential, the energy storage performances and electrocaloric effects of Ba_1-_xSr_xTiO₃ single crystals are obtained using the phase-field method. It is found that there is an optimal Sr concentration which maximizes the discharged energy density of a Ba_1-_xSr_xTiO₃ single crystal under an applied electric field. The electrocaloric effects of Ba_0.8Sr_0.2TiO₃, Ba_0.7Sr_0.3TiO₃, Ba_0.6Sr_0.4TiO₃, and Ba_0.5Sr_0.5TiO₃ single crystals are also predicted, from which the corresponding optimal temperatures are identified.
