title: Temperature and electric-field induced phase transitions, and full tensor properties of [011]C-poled domain-engineered tetragonal 0.63Pb(Mg1/3Nb2/3)-0.37PbTiO3single crystals.
abstract: The phase-transition sequence of 0.67Pb(Mg1/3Nb2/3)-0.37PbTiO3(PMN-0.37PT) single crystals driven by the electric (E) field and temperature is comprehensively studied. Based on the strain-Efield loop, polarization-Efield loop, and the evolution of domain configurations, theEfield along the [011]Cinduced phase transitions have been confirmed to be as follows: tetragonal (T) → monoclinic (MC) → single domain orthorhombic (O) phase. As theEfield decreases, the inducedOphase cannot be maintained and transformed to theMCphase, then to the coexistence state ofMCandTphases. In addition, the complete sets of dielectric, piezoelectric, and elastic constants for the [011]C-poled domain-engineered PMN-0.37PT single crystal were measured at room temperature, which show high longitudinal dielectric, piezoelectric, and electromechanical properties ([Formula: see text],d33= 1052 pC/N, andk33= 0.766). Our results revealed that theMCphase plays an important role in the high electromechanical properties of this domain-engineered single crystal. The temperature dependence of the domain configuration revealed that the volume fraction of theMCphase decreases with temperature accompanied by the reduction of [Formula: see text],d31, andk31due to the substantially smaller intrinsic properties of theTphase.
