Studies of Pb0.98Nb0.02[(Zr1-xSnx)0.97Ti3]1-zO3 (PZST x/3/2) were performed for 0≪x≪0.20 by electrically induced polarization and strain methods. Maximum electrically induced strains (Є) and polarizations (P) were found in the compositional range around x=0.15, where ferroelectric and antiferroelectric regions coexisted. In addition, these studies demonstrated evidence for two electrically induced phase transitions: (i) an antiferroelectric–ferroelectric near 40 kV/cm, and (ii) a secondary ferroelectric–ferroelectric near 60–80 kV/cm. The dominate contribution to Є was associated with the secondary transition, whereas the dominate contribution to P was associated with the first. © 1997 American Institute of Physics.
