Figure 5. (A) P-E and (B) current - electric field (I-E) hysteresis loops obtained at room temperature for PLSBZST thick-film ceramics; (C) E_AFE-FE, E_FE-AFE, ΔE, and P_max; (D) Weibull distribution of the four samples, with the inset showing the DBS as a function of x; (E) W_rec and η for four samples; (F) Comparison of the W_rec and η values of PLSBZST2 with those of recently reported AFE ceramics^{[11,29,30,34,35,50-59]}. P-E: Polarization - electric field; PLSBZST: (Pb_0.92-xLa_0.04Sr_xBa_0.02)(Zr_0.64Sn_0.35Ti_0.01)O₃; DBS: dielectric breakdown strength; AFE: antiferroelectric; P_max: maximum polarization; W_rec: recoverable energy storage density.
