“…It has to be noted that this strain at F R -F O transition is practically constant for various bias stress and electric field magnitude and frequency of the E ac drive [16]. This implies the displacement amplitude is practically independent of the supplied electrical power [18,19]. Therefore it illustrates relatively broadband capability of the transduction based on reversible FE phase transformation in mechanically confined relaxor single crystals.…”

“…However in PMN-PT crystals, the effect was more diffuse and continuous [13]. Later this elastic nonlinearity was also reported in different crystals and was shown to be a strong function of temperature and geometry of the crystals [16][17][18]. Recently, we demonstrated a large and reversible strain up to 0.5% at field of $0.1 MV m À1 in domain-engineered relaxor-FE PIN-PMN-PT single crystals [16].…”

Fundamental shortcomings of ferroelectrics (FEs) are low induced strain and high electric field often required for practical application in actuation, sensors, and acoustics. Although domain engineered FE single crystals deliver an order of magnitude improvement, fatigue remains another drawback in achieving reliable multiple domain switching crucial for memory storage. We demonstrate that under specially compressive stresses FE relaxors exhibit low field induced reversible and sustainable strain associated with FE-FE phase switching and unusual and unexpected lack of fatigue after several millions cycles is believed due to strain accommodation occurring in ferroics. Polarized light microscopy and X-ray diffraction are in a very good agreement with macroscopic observation and phenomenological model confirming proposed transformational path. The phenomena presented in this work are envisioned to be universal in domain engineered ferroics enabling mechanical stress to be used for strain and polarization control of electromechanical energy conversion.

“…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.…”

(PIN-PMN-PT) single crystals were studied under unpoled and [001]-poled conditions by Brillouin light scattering and dielectric spectroscopies. The unpoled crystal showed a diffused elastic anomaly accompanied by substantial dielectric dispersion, which were associated with the temperature evolution of polar nanoregions represented by the excitation of strong central peaks. The poled crystal exhibited two-step changes in both dielectric and elastic properties, which were attributed to the successive phase transitions from rhombohedral to tetragonal, and then from tetragonal to cubic phase upon heating. The high-temperature tetragonal-cubic phase transition remained diffused with dielectric dispersion due to local random fields inherent in relaxors. The transverse acoustic mode disappeared at the rhombohedraltetragonal phase transition indicating a clear symmetry change. V C 2012 American Institute of Physics.

Relaxor based ternary (0.60 -x)Pb(In 1/2 Nb 1/2 ) O 3 -0.40Pb(Mg 1/3 Nb 2/3 )-xPbTiO 3 ((0.60 -x)PIN-0.40PMN-xPT) polycrystalline ceramics were synthesized by twostep columbite precursor method. The effects of PIN/PT content on phase structure, microstructure, density, and dielectric, piezoelectric, ferroelectric and pyroelectric properties of the ternary ceramics were systematically investigated. A morphotropic phase boundary (MPB) near x = 0.34 was identified by X-ray diffraction and further confirmed by their respective electrical properties. Piezoelectric, ferroelectric and pyroelectric properties were enhanced for compositions near the MPB. The 0.26PIN-0.40PMN-0.34PT ceramics show optimum electrical properties: piezoelectric coefficient d 33 = 505 pC/N, planar electromechanical coupling factor k p = 62.5 %, remnant polarization P r = 32.1 lC/cm 2 , coercive field E c = 8.8 kV/cm, and room temperature pyroelectric coefficient p = 0.050 lC/cm 2°C . In addition, the rhombohedraltetragonal phase transition temperature T rt and Curie temperature T c of the ternary ceramics were identified by the temperature dependence of dielectric and pyroelectric measurements, which are much higher than those of binary PMN-PT ceramics, indicating the expanded temperature usage range of the ternary ceramics. The results show that this ternary system is a promising candidate for electromechanical applications with high performance and wide temperature usage range.
