Abstract

Two successive phase transitions, changing the crystal symmetry from rhombohedral to tetragonal, and then to cubic on a heating process, have been investigated in the Pb(Zn_1/3Nb_2/3)O₃ - PbTiO₃ single crystals with the composition near the morphotropic phase boundary. The existence of the morphotropic phase boundary has been confirmed by measuring the dielectric, piezoelectric and pyro-electric constant. Anomalously large electromechanical and piezoelectric constants are observed on the morphotropic phase boundary.
