title: Complete set of elastic, dielectric, and piezoelectric constants of [011]Cpoled rhombohedral Pb(In0.5Nb0.5)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3:Mn single crystals.
abstract: Mn modified rhombohedral Pb(In0.5Nb0.5)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3(PIN-PMN-PT:Mn) single crystals poled along [011]Ccrystallographic direction exhibit a "2R" engineered domain configuration, with macroscopicmm2symmetry. The complete sets of material constants were determined using combined resonance and ultrasonic methods, and compared to [001]Cpoled PIN-PMN-PT:Mn crystals. The thickness shear piezoelectric coefficientd15and electromechanical coupling factork15were found to be on the order of ∼3000 pC/N and 0.92, respectively, with longitudinal piezoelectric coefficientd33and coupling factork33being on the order of ∼1050 pC/N and 0.90. Of particular importance is that PIN-PMN-PT:Mn single crystals exhibited high mechanical quality factorQ33∼ 1000, comparable to "hard" PZT8 ceramics, which can also be confirmed by the low extrinsic contribution, being ≤2% from the Rayleigh analysis.
