Shear-mode piezoelectric properties of ternary Pb(In1/2Nb1/2)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3 single crystals

Abstract

A systematic study of the optimized orientation and temperature dependence of shear-mode piezoelectric properties for ternary Pb͑In 1/2 Nb 1/2 ͒O 3 -Pb͑Mg 1/3 Nb 2/3 ͒O 3 -PbTiO 3 ͑PIN-PMN-PT or PIMNT͒ piezocrystals was carried out. It was found that ͓111͔-poled samples presented the best shear piezoelectric properties when driving along ͓110͔ ͑the thickness direction͒. The electromechanical coupling coefficient k 15 and piezoelectric coefficient d 15 and g 15 were found to be 96.4%, 5966 pC/N, and 0.047 Vm/N, respectively, for optimum-cut samples with platinum ͑Pt͒ electrode. Besides, the maximum service temperature for shear mode is around 105°C, which is much higher than PMNT single crystals.

Phase transition behaviors in relaxor ferroelectric [001]-poled Pb(In1/2Nb1/2)O3-Pb(Mg1/3Nb2/3)O3-PbTiO3 single crystals studied by Brillouin light scattering and dielectric spectroscopies

“…Recently, various properties of PIN-PMN-PT single crystals near MPB including elastic, dielectric, and piezoelectric properties have been studied under different poling conditions. [9][10][11][12][13][14][15][16][17][18][19][20][21] However, the ferroelectric phase transition behaviors of PIN-PMN-PT single crystals have not been studied in detail. A great portion of the published data on this system are reported on poled samples at room temperatures, and studies on the phase transition behaviors in the temperature window of as-grown or unpoled samples in comparison with poled ones are scarce.…”

Growth and pyroelectric properties of rhombohedral 0.21Pb(In1/2Nb1/2)O3–0.49Pb(Mg1/3Nb2/3)O3–0.3PbTiO3 ternary single crystals

“…Recently, the melt Bridgman growth of xPb(In 1/2 Nb 1/2 ) O 3 -yPb(Mg 1/3 Nb 2/3 )O 3 -(1À xÀy)PbTiO 3 {PIMNT [100x/100y/100 (1À xÀy)]} ternary single crystals with large size and high quality have been reported, showing broadened temperature usage range (T RT 4100 1C) and comparable piezoelectric properties to those of PMNT crystals [9,10]. Furthermore, Yu et al [11] recently found that tetragonal PIMNT (41/17/42) ternary single crystals have relatively high T C of 253 1C compared with that of PMNT (62/38) crystals.…”

Composition and orientation dependence of high electric-field-induced strain in Pb(In1/2Nb1/2)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3 single crystals

“…[9][10][11][12][13][14] Yet, strain under high electric field was seldom studied systematically. In strain actuator design, it is important for the material to exhibit high strain values with low nonlinear hysteresis, which determines the actuator performance.…”
