a Wrec and η as functions of measurement temperature. The inset shows the P-E loops at different temperatures. b The temperature range in which η > 90% for 70BCT20-30BMZ ceramics and other relaxor ceramics. The number near each bar represents the room-temperature Wrec. c The cycling reliability was measured at 450 kV/cm and 200 °C up to 106 cycles. The inset shows the P-E loops after various cycles. d Variations of DC resistivity (ρDC) with temperature for (100-100x)BCT20-100xBMZ ceramics. The error bars represent the standard deviation. e Impedance complex plots of (100-100x)BCT20-100xBMZ ceramics at 400 °C. f Arrhenius plot of the bulk resistivity (ρIS) of 70BCT20-30BMZ ceramics.
