“…The results revealed the origin of the superior electromechanical properties in ͓001͔ poled PMN-33%PT multidomain crystals as from the large d 15 ͑PZN-PT͒ and (1 Ϫx)Pb(Mg 1/3 Nb 2/3 )O 3 -xPbTiO 3 ͑PMN-PT͒ ferroelectric single crystals has improved drastically since 1996, 1-4 and several complete data sets of PZN-PT and PMN-PT single crystals have been measured for different compositions.

The orientation dependence of piezoelectric properties has been calculated for 0.67Pb(Mn1/3Nb2/3)O3–0.33PbTiO3 (PMN–33%PT) single-domain crystals based on the measured full matrix properties. It is found that the maximum d33*=2411 pC/N and k33*=0.94 occur, respectively, in directions 63.0° and 70.8° from the spontaneous polarization direction. In [001] of the cubic coordinate, the rotated properties are d33*=2316 pC/N and k33*=0.93, respectively, comparable to the measured multidomain properties. The results revealed the origin of the superior electromechanical properties in [001] poled PMN–33%PT multidomain crystals as from the large d15 of the single-domain property.

“…The strain induced by the electrostrictive effect is generally small when compared with that induced by piezoelectricity, so a limited attention has been focused on it [124]. In the 1980's, a systematic study on electrostriction was carried out on relaxor ferroelectrics with perovskite structure, such as Pb However, the presence of lead oxides poses serious environmental and health concerns, especially during manufacturing and disposal after usage ; therefore, the research community is actively engaged in developing Pb-free alternatives [128,129].…”

The perovskite structure is one of the most wonderful to exist in nature. It obeys to a quite simple chemical formula, ABX 3 , in which A and B are metallic cations and X, an anion, usually oxygen. The anion packing is rather compact and leaves interstices for large A and small B cations. The A cation can be mono, di or trivalent, whereas B can be a di, tri, tetra, penta or hexavalent cation. This gives an extraordinary possibility of different combinations and partial or total substitutions, resulting in an incredible large number of compounds. Their physical and chemical properties strongly depend on the nature and oxidation states of cations, on the anionic and cationic stoichiometry, on the crystalline structure and elaboration techniques, etc.In this work, we review the different and most usual crystalline representations of perovskites, from high (cubic) to low (triclinic) symmetries, some well-known preparation methods, insisting for instance, in quite novel and original techniques such as the mechanosynthesis processing. Physical properties are reviewed, emphasizing the electrical (proton, ionic or mixed conductors) and catalytic properties of Mn-and Co-based perovskites ; a thorough view on the ferroelectric properties is presented, including piezoelectricity, thermistors or pyroelectric characteristics, just to mention some of them ; relaxors, microwave and optical features are also discussed, to end up with magnetism, superconductivity and multiferroïsme.Some materials discussed herein have already accomplished their way but others have promising horizons in both fundamental and applied research.To our knowledge, no much work exists to relate the crystalline nature of the different perovskite-type compounds with their properties and synthesis procedures, in particular with the most recent and newest processes such as the mechanosynthesis approach. Although this is not intended to be a full review of all existing perovskite materials, this report offers a good compilation of the main compounds, their structure and microstructure, processing and relationships between these features.

“…10 First, perovskite crystals, in general, possess the highest elastic stiffness constant c 33 D along the pseudo-cubic h111i body diagonals, since the anisotropy factor A [A ¼ 2c 44 /(c 11 -c 12 )] 11 is larger than 1, as given in Table I. 10,[12][13][14] Therefore, perovskite crystals oriented along the [111] direction are selected to achieve a high frequency constant N 33 . Second, the special ferroelectric phase for [111]-oriented crystals, in which high dielectric permittivities present, must be identified.…”

Shrout, T. R. (2016).[111]-oriented PIN-PMN-PT crystals with ultrahigh dielectric permittivity and high frequency constant for high-frequency transducer applications. Journal of Applied Physics, 120 (7), 074105-1-074105-5.[111]-oriented PIN-PMN-PT crystals with ultrahigh dielectric permittivity and high frequency constant for high-frequency transducer applications AbstractThe electromechanical properties of [111]-oriented tetragonal Pb(In1/2Nb1/2O3)-Pb(Mg1/3Nb2/3O3)-PbTiO3 (PIN-PMN-PT) crystals were investigated for potential high frequency ultrasonic transducers. The domain-engineered tetragonal crystals exhibit an ultrahigh free dielectric permittivity ε33 T > 10 000 with a moderate electromechanical coupling factor k33 ∼ 0.79, leading to a high clamped dielectric permittivity ε33 S of 2800, significantly higher than those of the rhombohedral relaxor-PT crystals and high-K (dielectric permittivity) piezoelectric ceramics. Of particular significance is that the [111]-oriented tetragonal crystals were found to possess high elastic stiffness, with frequency constant N33 of ∼2400 Hz m, allowing relatively easy fabrication of high-frequency transducers. In addition, no scaling effect of piezoelectric and dielectric properties was observed down to thickness of 0.1 mm, corresponding to an operational frequency of ∼24 MHz. These advantages of [111]-oriented tetragonal PIN-PMN-PT crystals will benefit high-frequency ultrasonic array transducers, allowing for high sensitivity, broad bandwidth, and reduced noise/crosstalk.
