The piezoelectric characteristics were investigated in the field‐induced ferroelectric phase of the antiferroelectric Pb0.99 Nb0.02[(Zr0.6Sn0.4) 1 −yTiy]0.98O3 family. The electromechanical coupling factors kp and kt were measured, and the piezoelectric anisotropy was calculated. The piezoelectricity was controlled easily by the applied electric field pulse. The large piezoelectric anisotropy of these materials in comparison to that of conventional PZT piezoelectric materials makes them very applicable for ultrasonic probes and surface acoustic wave filters.
