Abstract

Previous work on the solid solution x.PbZrO₃[PZ]-y. Pb(Zn_1/3Nb_2/3)O₃ [PZN]-z.PbTiO₃ [PT] (PZNT) has shown a DC-field-induced ferroelectric-antiferroelectric (AF-FE) transition. The authors explore the electrical field dependence of the elastic constant (s^E ₁₁), piezoelectric coefficient (d₃₁), and dielectric constant (K₃₃) near this phase transition. Hysteresis results indicate that the location of the AF-FE boundary is between x=92.8% and x=93.2% PZ. Room-temperature dielectric constants near 250 have been measured and can be altered with suitable compositional adjustments. The PZZN phase diagram (PZNT with 0 mol.% PT) has been refined, showing that the AF-FE boundary at room temperature is PZZN(93.2) and PZZN(93.0)
