Domain configuration and ferroelectric related properties of the (110)(cub) cuts of relaxor-based Pb(Mg1/3Nb2/3)O-3-PbTiO3 single crystals

Domain configuration and ferroelectric related properties of Pb(Mg1/3Nb2/3)O-3-PbTiO3 were investigated as a function of applied electric field for the (110)(cub) cuts. It was found that a single domain orthorhombic state could be achieved by applying an electric field along the direction (110)(cub), but the state after removing the electric field strongly depends on the composition and electric field. A qualitative analysis revealed that a slight variation in composition near morphotropic phase boundaries or in an electric field has a significant influence on domain configuration and piezoelectricity for the (110)(cub) cuts in Pb(Mg1/3Nb2/3)O-3-PbTiO3.
