Phase-field simulation of electrocaloric effect in textured Ba<sub>0.8</sub>Sr<sub>0.2</sub>TiO<sub>3</sub> polycrystalline ceramics

Figure 5. (A) The P-E loop curves of BST80 polycrystalline for sample 1, along with three sets of random orientation angles for samples 5, 6, and 7. The regions I-VI depicted in panel (B) illustrate the microscopic domain morphology at various phases of the P-E loop, encompassing scenarios both with and without the incorporation of textured ceramics, as shown in panel (A). The different colors observed within the ferroelectric domains represent the various types of domain structures, each characterized by distinct orientations. (C) The relationship curve between ΔT and temperature (T) generated by the BST80 polycrystalline under an electric field strength of 1 MV·m^-1 for six sets of random orientation angles. BST80: Ba_0.8Sr_0.2TiO₃; ΔT: temperature change.
