Figure 7. (A) P-E loops of all NBBSCT-xMN compositions under 400 kV/cm. (B) P-E loops measured at respective breakdown electric fields for each composition. (C) Composition-dependent energy storage properties. (D) Electric field dependence of P-E loops and (E) calculated Wrec and η for NBBSCT-3MN ceramics. (F) Comparison of Wrec and η between NBBSCT-3MN ceramic and reported lead-free perovskite bulk ceramics[8,26,36,38-47].
