Abstract
Temperature and field dependences of the dielectric permittivity (ɛ) and unipolar electric field-induced strain (S) of PbFe1/2Nb1/2O3, PbSc1/2Nb1/2O3, and 0.91PbFe1/2Nb1/2O3–0.09PbTiO3 solid solution ceramics are studied in the temperature range from 25 to 160 °C. Using these experimental data, both the effective d*33eff = Smax/Emax and differential d*33dif = dS/dE converse piezoelectric moduli are calculated, and (E, T) diagrams were plotted. The possible critical behavior of the converse piezoelectric modulus d*33 and its correlation with the position of the known critical points in the (E, T) diagrams of studied ceramics are discussed.
