Abstract: In this work, PZ-PNN ceramic was prepared by a columbite method and sintered at optimum temperature. The effect of uniaxial compressive stress on the hysteresis properties of PZ-PNN ceramics is investigated. The hysteresis loop and ferroelectric properties under the compressive stress of the ceramics are observed at stress up to 100 MPa using a compressometer in conjunction with a modified Sawyer-Tower circuit. The results show that the applied stress has a significant influence on the hysteresis of PZ-PNN ceramics. The ferroelectric characteristics, i.e. the area of loops, Ps and Pr decrease with increasing compressive stress. Copyright © Taylor & Francis Group, LLC.
