Effects of perpendicular compressive stress on the ferroelectric properties of ceramics in PZT-PZN system were investigated. The (1-x)Pb(Zr_(1/2)Ti(1/2))O_(3-x)Pb(Zn_(1/3)Nb_(2/3))O_3 or (1-x)PZT- (x)PZN (x = 0.1-0.5) ceramics were prepared by a conventional mixed-oxide method. The ferroelectric properties were measured under compressive stress applied perpendicular to an electric field direction at stress levels up to 90 MPa using a compressometer in conjunction with a modified Sawyer-Tower circuit. It was found that with increasing compressive stress the area of the ferroelectric hysteresis (P-E) loops, the maximum polarization (P_(max)), and the remanent polarization (P_r) decreased, while the coercive field (E_c) remained relatively constant. These results were interpreted through the domain switching, clamping of domain walls and de-poling mechanisms.
