(Pb0.832Ba0.138La0.02)(Zr0.7Ti0.05Sn0.25)O3 ceramics with stable antiferroelectric phase at room temperature were fabricated by Mn doping. The enhancement of antiferroelectric phase is attributed that the substitution of Mn ion into the B site decreased tolerance factor of the ceramics. The largest pyroelectric figure of merit of 25 × 10−5 Pa−0.5 was obtained in (Pb0.832Ba0.138La0.02)(Zr0.7Ti0.05Sn0.25)O3 antiferroelectric ceramics with 0.2 mol. % Mn doping, which is far higher than that of convention phase transition materials. The increase of the pyroelectric response was attributed to the improvement in dc field-induced dielectric enhancement effect and the reduction in dielectric loss.
