Schematic diagram of (a) Low-entropy model and (b) high-entropy model. c Three-dimensional domain structures of the 0.85R and 2.17R models under different electric fields by phase-field simulation. Simulated P-E loops of (d) the 0.85R and (e) 2.17R models. The insets illustrate domain states before and after electric field application. f Simulated evolution of Pr and Eb as functions of Sconfig. g Simulated evolution of Wrec and η as functions of Sconfig.
