Fig. 3: Electrical properties of the (BiBaNaFeTiNb)O bulk ceramic.
From: A highly polarizable concentrated dipole glass for ultrahigh energy storage
a Temperature-dependent relative dielectric constant εr and loss tangent tan δ at different f. b P-E loops of x = 0.12, 2/9 ((BiBaNaFeZrNb)O) and (BiBaNaFeZrNb)O samples. c The comparison of the Wrec, η and Pm of (BiBaNaFeTiNb)O (HPCDG) with the x = 0.12 (canonical RFE) and (BiBaNaFeZrNb)O (DG) samples. Numbers 1, 2, 3 represent the x = 0.12, (BiBaNaFeTiNb)O, and (BiBaNaFeZrNb)O samples, respectively. d P-E loop of (BiBaNaFeTiNb)O measured at 67 kV mm−1. The inset is the evolution of Pm, Pr, and ΔP (Pm-Pr) as a function of electric field. e The comparison of the dynamic scaling behavior of our sample with that of representative RFEs9,13,40,41. f The evolution of total energy density Wtotal, Wrec, and η of the (BiBaNaFeTiNb)O bulk ceramic as a function of electric field.
