    Abstract

    We characterized the temperature dependent ( 25-200°C) electromechanical properties and crystal structure of Pb(In1/2Nb 1/2)O3-Pb(Mg1/3Nb2/3)O 3-PbTiO3 single crystals using in situ electrical measurement and neutron diffraction techniques. The results show that the poled crystal experiences an addition phase transition around 120°C whereas such a transition is absent in the unpoled crystal. It is also found that the polar order persists above the maximum dielectric permittivity temperature at which the crystal shows a well-defined antiferroelectric behavior. The changes in the electrical properties and underlying crystal structure are discussed in the paper.
