Abstract

Crystals of Co-doped 0.92Pb(Zn_1/3Nb_2/3)O₃-0.08PbTiO₃ (PZNT) were grown by modified flux technique. The dielectric and piezoelectric properties were investigated for <001> oriented crystals. Under high power resonant drive, the mechanical quality factor (Q_m) and vibration velocity showed a considerable improvement, compared to the unmodified PZNT crystals. Unhysteretic unipolar strain-electric field response was obtained for field levels of 30-kV/cm with strain level of ∼0.3%. Co-doping resulted in the increment of electric field level required for rhombohedral to tetragonal phase transition. The curie temperature of Co-modified crystals was ∼130°C. The results obtained in this study indicate that Co imparts hardening effect in the PZNT crystal.
