TL;DR: In this paper, single crystals in the lead magnesium niobate-lead titanate-(1−x) Pb(Mg1/3 Nb2/3)O3-(x), PbTiO3 solid solution system were grown using a flux growth technique.
Abstract: Single crystals in the lead magnesium niobate-lead titanate-(1−x) Pb(Mg1/3 Nb2/3)O3-(x) PbTiO3 solid solution system were grown using a flux growth technique. Crystals over the compositional range of 0.3 ≤ ′ ≤ 0.4 being near the rhombohedra1 (pseudo-cubic)-tetragonal morphotropic phase boundary were characterized. The dielectric behavior along the pseudo cubic [111] and [100] directions were measured as a function of temperature and frequency. The effect of poling was also examined.

TL;DR: The first ferroelectric Langmuir-Blodgett films were prepared and investigated for the first time in this article, using a copolymer of vinylidene fluoride with trifluorethylene.
Abstract: The ferroelectric Langmuir-Blodgett films are prepared and investigated for the first time The films are prepared from the ferroelectric copolymer of vinylidene fluoride with trifluorethylene The films with the thickness off 150 A show the pyroelectric effect being measured along the polar C-axis perpendicular to the substrate surface, partial remnant polarization switching and ferroelectric phase transition of the first order, characterized by the temperature hysteresis

TL;DR: Flexible piezoelectric composites made from PZT and polymer with 0-0-3 connectivity were fabricated using several types of Eccogel polymer in this paper.
Abstract: Flexible piezoelectric composites made from PZT and polymer with 0–0–3 connectivity were fabricated using several types of Eccogel polymer. The conductivity of the composite is controlled by adding small amounts of a semiconductor filler such as carbon, germanium or silicon. By controlling conductivity, poling can be carried out very rapidly at low voltages, resulting in properties comparable to composites prepared without a conductive phase. For composites optimized for hydrophone performance, the hydrostatic voltage coefficient [gbar]h and hydrostatic figure of merit [gbar]h[dbar]h are an order of magnitude larger than those of single phase PZT.

TL;DR: In this article, the Raman spectra of bismuth sodium titanate in its rhombohedral, tetragonal, and cubic phases were measured, with special attention paid to the phase transitions at 584K and 837K (heating).
Abstract: We have measured the Raman spectra of bismuth sodium titanate in its rhombohedral, tetragonal, and cubic phases, with special attention paid to the phase transitions at 584K and 837K (heating). Both transitions appear to be order-disorder and strongly first order, with large thermal hysteresis. The phonon spectra at temperature slightly below the tetragonal phase are remarkably similar to BaTiO3 with A1(To) modes at 130, 269, and 541 cm−1 (compared with 170, 270, 520 cm−1 in BaTiO3) and an E(TO) at 52 cm−1.

TL;DR: In this article, the additive influence of Zn and In on optical properties of LiNbO3 was investigated and it was shown that In can be regarded as a relative of optical damage resistant Me impurities (Me = Mg, Zn, In…)
Abstract: LiNbO3 crystals codoped with Zn and In demonstrate some properties which are characteristic of LiNbO3 doped with optical damage resistant impurities Mg or Zn with concentrations above the ‘threshold’ values. The additive influence of Zn and In on optical properties of LiNbO3 indicates that In can be regarded as a relative of optical damage resistant Me impurities (Me = Mg, Zn, In…)
