Abstract

(Pb0.89Ba0.08La0.02)(Zr0.50Sn0.40Ti0.10)O3 multi-layer antiferroelectric ceramics with uniform and dense microstructure were fabricated by a rolling process. The nature of AFE was proved by the double hysteresis loops and the double-butterfly C–V curves. High dielectric tunability was observed at low electric flied, as high as 24% at 11 kV/cm, or 2% per kV/cm, together with low dielectric loss. The results demonstrated that the rolling process is a feasible approach to fabricate multi-layer ceramics, and the multi-layer ceramics had a promising potential in tunable devices.
