摘要

In this work, a simple method to improve the dielectric tunability of antiferroelectric ceramics was introduced, and (Pb_(0.97-x)La_(0.02))Ba_x)(Zr_(0.50)Sn_(0.40)Ti_(0.10))O_3 (x = 0.08, 0.09, 0.10) antiferroelectric ceramics were prepared by conventional solid-state route. The effect of Ba-modification on phase structure and electric properties was systematically investigated. The results revealed that the barium content contributed to the decline of the Curie temperature and enhanced dielectric tunable performance. All compositions exhibited butterfly curve, and a high tunability of 48.89% at E_(AF) and 53.02% at E_(FA) was obtained in (Pb_(0.87)La_(0.02)Ba_(0.10))(Zr_(0.50)Sn_(0.40)Ti_(0.10))O_3. In addition, the ε_(max)/ε_(min) ratio was up to 25.32, making it a promising candidate for nonlinear tunable devices.
