Abstract Single-domain structure with orthorhombic symmetry has been achieved in morphotropic phase boundary composition 0.24Pb(In1/2Nb1/2)O3 -0.43Pb(Mg1/3Nb2/3)O3-0.33PbTiO3 ternary single crystal by applying a large field along the pseudo-cubic direction [011]c. Complete set of elastic, piezoelectric, and dielectric constants has been determined with self-consistency. This crystal shows very large thickness shear piezoelectric coefficient d15=4324 pC/N and extremely high shear electromechanical coupling factor k15=96%. Three-dimensional orientation dependence of the longitudinal piezoelectric constant d33 was calculated and compared with experimental values, which revealed nearly 20% extrinsic contributions in domain engineered [001]c and [111]c poled conditions.
