Figure 9. Polarization response and macroscopic properties of ceramics with different phase structures. (A) Schematic showing the dielectric constant as a function of temperature for BNST-xFN ceramics, with BNST, BNST-0.01FN, and BNST-0.03FN represented at distinct positions along the curve. (B) Initial domain structure, polarization response under an applied electric field, and after field removal for BNST ceramic. (C) P-E loops, S-E curve and J-E curve of BNST ceramic. (D) Initial domain structure, polarization response under an applied electric field, and after field removal for BNST-0.01FN ceramic. (E) P-E loops, S-E curve and J-E curve of BNST-0.01FN ceramic. (F) Initial domain structure, polarization response under an applied electric field, and after field removal for BNST-0.03FN ceramic. (G) P-E loops, S-E curve and J-E curve of BNST-0.03FN ceramic.
