Title: Effects of composition and temperature on the large field behavior of [011]{sub C} relaxor ferroelectric single crystals

Abstract

The large field behavior of [011]{sub C} cut relaxor ferroelectric lead indium niobate–lead magnesium niobate–lead titanate, xPb(In{sub 1/2}Nb{sub 1/2})O{sub 3}-(1-x-y)Pb(Mg{sub 1/3}Nb{sub 2/3})O{sub 3}-yPbTiO{sub 3}, single crystals was experimentally characterized in the piezoelectric d{sub 322}-mode configuration under combined mechanical, electrical, and thermal loading. Increasing the concentration of lead indium niobate and decreasing the concentration of lead titanate in compositions near the morphotropic phase boundary resulted in a decrease of mechanical compliance, dielectric permittivity, and piezoelectric coefficients as well as a shift from a continuous to a discontinuous transformation.

  • Optical properties and phase transitions of Pb(In{sub 1∕2}Nb{sub 1∕2})O{sub 3}-Pb(Mg{sub 1∕3}Nb{sub 2∕3})O{sub 3}-PbTiO{sub 3} (PIN-PMN-PT) crystals near morphotropic phase boundary (MPB) have been investigated by temperature dependent transmittance and reflectance spectra. Three critical point energies E{sub g} = 3.17–3.18 eV, E{sub a} = 3.41–3.61 eV, and E{sub b} = 4.74–4.81 eV can be assigned to the transitions from oxygen 2p to titanium d, niobium d, and lead 6p states, respectively. They show narrowing trends with increasing temperature, which can be caused by thermal expansion of the lattice and electron-phonon interaction. Deviation from the linear behaviors can be observed from E{sub a} and E{sub b} versus PT concentration, indicating amore » complex multiphase structure near MPB region.« less
  • We have fabricated magnetoelectric heterostructures by growing ferromagnetic La{sub 1-x}Ba{sub x}MnO₃ (x=0.2, 0.4) thin films on (001)-, (110)-, and (111)-oriented 0.31Pb(In{sub 1/2}Nb{sub 1/2})O₃-0.35Pb(Mg{sub 1/3}Nb{sub 1/2})O₃-0.34PbTiO₃ (PINT) ferroelectric single-crystal substrates. Upon poling along the [001], [110], or [111] crystal direction, the electric-field-induced non-180° domain switching gives rise to a decrease in the resistance and an enhancement of the metal-to-insulator transition temperature T C of the films. By taking advantage of the 180° ferroelectric domain switching, we identify that such changes in the resistance and T C are caused by domain switching-induced strain but not domain switching-induced accumulation or depletion of chargemore » carriers at the interface. Further, we found that the domain switching-induced strain effects can be efficiently controlled by a magnetic field, mediated by the electronic phase separation. Moreover, we determined the evolution of the strength of the electronic phase separation against temperature and magnetic field by recording the strain-tunability of the resistance [(ΔR/R){sub strain}] under magnetic fields. Additionally, opposing effects of domain switching-induced strain on ferromagnetism above and below 197 K for the La₀.₈Ba₀.₂MnO₃ film and 150 K for the La₀.₆Ba₀.₄MnO₃ film, respectively, were observed and explained by the magnetoelastic effect through adjusting the magnetic anisotropy. Finally, using the reversible ferroelastic domain switching of the PINT, we realized non-volatile resistance switching of the films at room temperature, implying potential applications of the magnetoelectric heterostructure in non-volatile memory devices.« less
  • The piezoelectric properties of relaxor based ferroelectric single crystals, such as Pb(Zn{sub 1/3}Nb{sub 2/3})O{sub 3}{endash}PbTiO{sub 3} and Pb(Mg{sub 1/3}Nb{sub 2/3})O{sub 3}{endash}PbTiO{sub 3} were investigated for electromechanical actuators. In contrast to polycrystalline materials such as Pb(Zr,Ti)O{sub 3}, morphotropic phase boundary compositions were not essential for high piezoelectric strain. Piezoelectric coefficients (d{sub 33}{close_quote}s){gt}2500pC/N and subsequent strain levels up to {gt}0.6{percent} with minimal hysteresis were observed. Crystallographically, high strains are achieved for {l_angle}001{r_angle} oriented rhombohedral crystals, although {l_angle}111{r_angle} is the polar direction. Ultrahigh strain levels up to 1.7{percent}, an order of magnitude larger than those available from conventional piezoelectric and electrostrictive ceramics, couldmore » be achieved being related to an E-field induced phase transformation. High electromechanical coupling (k{sub 33}){gt}90{percent} and low dielectric loss {lt}1{percent}, along with large strain make these crystals promising candidates for high performance solid state actuators. {copyright} {ital 1997 American Institute of Physics.}« less
  • Optimal properties like piezoelectricity can be found in polarizable materials for which the structure changes sharply under small composition variations in the vicinity of their morphotropic phase boundary or the triple point in their isobaric temperature-composition phase diagram. In the latter, lead-free (Ba{sub 0.850}Ca{sub 0.150})(Ti{sub 0.900}Zr{sub 0.100})O{sub 3} ceramics exhibit outstanding piezoelectric coefficients. For the first time, we report the growth of piezoelectric lead-free single crystals in the BaTiO{sub 3}-BaZrO{sub 3}-CaTiO{sub 3} pseudo-ternary system. The stoichiometry control in the CaO-BaO-TiO{sub 2}-ZrO{sub 2} solid solution led to single crystals with various compositions ranging from (Ba{sub 0.857}Ca{sub 0.143})(Ti{sub 0.928}Zr{sub 0.072})O{sub 3} tomore » (Ba{sub 0.953}Ca{sub 0.047})(Ti{sub 0.427}Zr{sub 0.573})O{sub 3}. We evidenced a continuous cross-over from a ferroelectric state at high titanium content to a relaxor one on increasing the zirconium content. Such a property tuning is rather seldom observed in lead-free ferroelectrics and confirms what was already reported for ceramics. Single crystal with (Ba{sub 0.838}Ca{sub 0.162})(Ti{sub 0.854}Zr{sub 0.146})O{sub 3} composition, which has been grown and oriented along [001] crystallographic direction, displayed electromechanical coefficients d{sub 31} and k{sub 31} of 93 pC.N{sup −1} and 0.18, respectively, near the room temperature (T = 305 K)« less
  • Ferroelectric phase inducing threshold electric field E{sub th} and its temperature dependence were determined in relaxor ferroelectric 0.87Pb(Mg{sub 1/3}Nb{sub 2/3})O{sub 3}-0.13PbTiO{sub 3} (PMN-13PT) ceramics by measuring dielectric response on a dc field pulse. Evolution of the induced ferroelectricity was observed by means of polarization measurements. An inducing threshold field was found to have a minimum of E{sub th,min}=1.55 kV/cm at T=-5 deg. C. In contrast to pure PMN, which shows a minimum threshold field near the depolarization temperature, the temperature of the minimum threshold field differs by an amount of {delta}T=23 deg. C from the depolarization temperature T{sub dp}=18 deg.more » C in PMN-13PT.« less
