A complete set of material properties of single domain 0.26Pb(In1∕2Nb1∕2)O3–0.46Pb(Mg1∕3Nb2∕3)O3–0.28PbTiO3 single crystals

摘要

Pb(In1∕2Nb1∕2)O3–Pb(Mg1∕3Nb2∕3)O3–PbTiO3 (PIN-PMN-PT) single crystals have been developed recently, which can increase the operating temperature by at least 20 °C compared to PMN-PT crystals. We have measured a complete set of material properties of single domain PIN-PMN-PT crystal, which is urgently needed in theoretical studies and electromechanical device designs using this crystal. Because the rotated values of d33*=1122 pC∕N and k33*=89% along [001]c calculated using the single domain data obtained here are in good agreement with the [001]c poled multidomain PIN-PMN-PT crystals, one may conclude that the physical origin of the ultrahigh piezoelectric properties mainly come from orientation effect.
