Anomaly in dielectric and piezoelectric properties of (1−x)Pb[Mg1/3Nb2/3]O3–xPbZrO3 ceramic

(1−x)Pb(Mg1/3Nb2/3)O3–xPbZrO3 ceramic has been investigated for dielectric and piezoelectric behavior for the complete solid solution range. The dielectric constant (ε′ε′), coupling coefficient (k31)(k31) and piezoelectric strain coefficient (d33)(d33) show anomaly in the composition range of 0.40
