摘要：

The temperature dependence of the coupling constants k(mu nu) and piezoelectric constants d(mu nu), g(mu nu) of transverse and shear mode 0.71Pb(Mg1/3Nb2/3)O-3-0.29PbTiO(3) (PMN-29% PT) single crystals with optimal orientation from room temperature to 115 degrees C were reported. From 20 degrees C to approximately 80 degrees C, k(31) increases slightly from 91.0% to 93.5%, while d(31) increases from 1900.0 to 4500.0 pC N-1. When the temperature exceeds 80 degrees C, both k(31) and d(31) begin to drop. Similarly, the coupling factor k(15) increases from 95% to 97%, while the piezoelectric constant d(15) increases from 4769.4 to 14293.2 pCN(-1) when the temperature rises from room temperature to 93 degrees C. When the temperature goes beyond 93 degrees C, the shear-mode piezoelectric properties start to decay. We also study the temperature dependence of the elastic compliances s(11)(E) and s(55)(E), both of which show strong dependence of the temperature. The service temperature for PMN-29% PT is determined to be lower than 80 degrees C for transverse vibration and lower than 93 degrees C for shear-mode samples. These would effectively guide the correlative device designs and practical applications.
