Complete set of material constants of Pb(In1/2Nb1/2)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3 single crystal with morphotropic phase boundary composition

Abstract

Using combined resonance and ultrasonic methods, a full set of material constants has been measured for morphotropic phase boundary (MPB) composition xPb(In1/2Nb1/2)O3–(1−x−y)Pb(Mg1/3Nb2/3)O3–yPbTiO3 (PIN-PMN-PT) single crystals poled along [001]c. Compared with the MPB composition (1−x)Pb(Mg1/3Nb2/3)O3–xPbTiO3 (PMN-PT) single crystals, the PIN-PMN-PT single crystals have smaller anisotropy, higher Curie temperature (Tc≈197 °C), and higher rhombohedral to tetragonal phase transition temperature (TR-T≈96 °C). The electromechanical properties obtained here are the best found so far for this ternary system with d33≈2742 pC/N, d31≈−1337 pC/N, k33≈95%, and k31≈65%.

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.…”

Characterization of full set material constants of piezoelectric materials based on ultrasonic method and inverse impedance spectroscopy using only one sample

“…[2][3][4][5][6][7][8] It is worth mentioning that better accuracy could be obtained by ultrasonic method than the resonance method. 6,14 But only a few independent constants can be measured from one sample by the pulse-echo ultrasonic method. In this paper, we reported a methodology by combining the ultrasonic and inverse impedance spectroscopy method to obtain all constants using only one sample, which guarantees self-consistency.…”

“…[1][2][3][4][5][6][7][8][9][10][11][12] In modern device design, finite element software packages are routinely used, which need to have the complete set of material properties of constituent materials as input. The accuracy of these material constants determines the accuracy of the design simulation.…”

Determination of full set material constants of [011]c poled 0.72Pb(Mg1/3Nb2/3)O3-0.28PbTiO3 single crystal from one sample

“…[21][22][23] Better accuracy can be achieved by ultrasonic method than resonance method. 4 Hence, some elastic constants were first measured by the ultrasonic pulse-echo method in our experiments. A 20 MHz shear wave transducer and a 15 MHz longitudinal wave transducer were excited by a Panametrics Here, the superscript on the shear velocity v it represents the vibration direction of the shear wave.…”

“…[1][2][3][4][5] Compared with [001] c poled single crystals, [011] c poled single crystals exhibit superior transverse and shear electromechanical properties, and they have been used in next generation transverse mode sensors and actuators. 6,7 For device designs and fundamental studies, knowing the complete set of material properties with self-consistency is crucial.…”
