“…The higher coercive filed of the present crystals is attributed to the domain motion prevented by the oxygen vacancies. The results are similar to those of the Er 3+ doped PMN-PT and PSN-PMN-PT crystals [18,19].…”

“…The absorption spectra of the PEN-PMN-PT crystals is similar as other Er 3+ -doped ferroelectric materials [25,26]. PSN-PMN-PT crystals [18,19]. Moreover, previous reports indicated that coercive filed of PZN-PYN-PT ceramic in MPB regions is mainly dependent on the tetragonal phase and have been improved with increasing of content of the tetragonal phase [22].…”

“…As a result, it is believed that the ratio of the rhombohedral and tetragonal phases in the present crystals is the reason of the difference of ferroelectric properties. [18,19]. Moreover, previous reports indicated that coercive filed of PZN-PYN-PT ceramic in MPB regions is mainly dependent on the tetragonal phase and have been improved with increasing of content of the tetragonal phase [22].…”

“…Li et al [17] explored new ternary crystals Pb(Ho 1/2 Nb 1/2 )O 3 -Pb(Mg 1/3 Nb 2/3 )O 3 -PbTiO 3 (PHN-PMN-PT) with the E c and T c of 3.22 kV/cm and 140 • C, respectively. The E c~8 .17 kV/cm and T c~1 48 • C were achieved in 6PSN-63PMN-31PT by He et al [18]. These results indicate that the Curie temperature and coercive field of the PMN-PT crystals can be improved with the appropriate cations.…”

New ferroelectric crystals Pb(Er1/2Nb1/2)-Pb(Mg1/3Nb1/3)O-PbTiO3 (PEN-PMN-PT) were grown by using the flux method. Phase structure of the crystals was described by the X-ray diffraction analysis. Dielectric, ferroelectric and optical properties of the PEN-PMN-PT crystals were investigated systematically. Higher Curie temperature (Tc ~ 291 °C) and larger coercive field (Ec ~ 17.6 kV/cm) for the 40PEN-13PMN-47PT can be obtained, respectively, compared with those of the PMN-PT. Moreover, strong green and red emissions can be excited by using the 980 nm laser. The PEN-PMN-PT crystals with these performances have some promising applications in the electromechanical and optical devices.

“…Moreover, the importance of MPB composition in the piezoelectric response should be emphasized. Xi et al 7 , 38 reported that in 0.06PSN–0.63PMN–0.31PT single crystals, although with a large coercive field of 8.17 kV/cm, the maximum piezoelectric constant is only ~1200 pC/N, which is similar to that of PZT ceramics or lead-free crystals. Guo et al 39 reported that 0.05PSN–0.63PMN–0.32PT single crystals in R phase exhibit inferior performance with d 33 = 1200 pC/N and ε 33 ~ 3500.…”

A large coercive field (EC) and ultrahigh piezoelectricity are essential for ferroelectrics used in high-drive electromechanical applications. The discovery of relaxor-PbTiO3 crystals is a recent breakthrough; they currently afford the highest piezoelectricity, but usually with a low EC. Such performance deterioration occurs because high piezoelectricity is interlinked with an easy polarization rotation, subsequently favoring a dipole switch under small fields. Therefore, the search for ferroelectrics with both a large EC and ultrahigh piezoelectricity has become an imminent challenge. Herein, ternary Pb(Sc1/2Nb1/2)O3–Pb(Mg1/3Nb2/3)O3–PbTiO3 crystals are reported, wherein the dispersed local heterogeneity comprises abundant tetragonal phases, affording a EC of 8.2 kV/cm (greater than that of Pb(Mg1/3Nb2/3)O3–PbTiO3 by a factor of three) and ultrahigh piezoelectricity (d33 = 2630 pC/N; d15 = 490 pC/N). The observed EC enhancement is the largest reported for ultrahigh-piezoelectric materials, providing a simple, practical, and universal route for improving functionalities in ferroelectrics with an atomic-level understanding.
