A complete set of material properties of single domain 0.26Pb (In 1/2 Nb1/2) O3 -0.46Pb (Mg1/3 Nb 2/3) O3 -0.28 PbTiO3 single crystals

Abstract

Pb (In1/2 Nb1/2) O3 -Pb (Mg1/3 Nb2/3) 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. © 2010 American Institute of Physics.
