Summary: The enhanced flexoelectric-like effect in oxide semiconductors has properties comparable to high-K materials and has led to research aimed at enhancing the flexoelectricity of these materials. However, the effective flexoelectric coefficient approaches limits under different doping methods, indicating the need to address fundamental questions. In this study, the researchers revisited the origin of the flexoelectric-like effect in oxide semiconductors and found that the effective flexoelectric coefficient of Nb-doped SrTiO3 single crystals increases with a larger doping concentration of Nb. Additionally, the presence of oxygen vacancies has a crucial impact on flexoelectricity at low frequencies.

Summary: Under the application of an external voltage, high electric field concentrations develop around the interdigitated electrode edges inside multilayer ceramic actuators (MLCAs). The local inhomogeneity in the electromechanical response is caused by the spatial distribution of the local electrical field. By utilizing synchrotron-based high-energy X-ray diffraction (XRD), the structural changes in partially electroded Nb-doped PbZrxTi1-xO3 samples as a function of applied electric field were investigated. The results show that the domain switching behavior and phase transitions are spatially dependent across the inactive regions in partially electroded samples, especially near the electrode edge and the tetragonal composition near the morphotropic phase boundary (MPB).

Summary: The effects of multiwall carbon nanotubes (MWCNTs) on the electrical, dielectric, and piezoelectric properties of the ferroelectric ceramic/castor-oil polyurethane (PUR) composite films were investigated. The addition of MWCNTs significantly enhanced the electrical and piezoelectric properties of the composite films by acting as conductive bridges between the lead zirconate titanate (PZT) particles. The dispersion of MWCNT nanoparticles also improved the poling effectiveness and increased the d(33) coefficient of the three-phase piezoelectric composites.

Summary: This work investigates the laser-based annealing process of sol-gel-derived PZT53/47 thin films and demonstrates that the crystallization time of chemical solution deposited PZT thin films can be significantly reduced by using laser radiation. The study also reveals that short interaction times during laser annealing shift the nucleation of the PZT thin films from epitaxial to heterogeneous nucleation.

Summary: Neutron diffraction in conjunction with isotopic substitution on Ni-62(43) (63)Cu(57) indicates chemical short-range order in the stable liquid, shown by oscillations in the concentration-concentration structure factor S CC(q). This suggests a non-ideal solution behavior of Ni-Cu contradicting common belief, but supported by measurements of free enthalpy of mixing. The temperature dependence of S-CC at small momentum transfer provides evidence of critical compositional fluctuations in Ni43Cu57 melts.

Summary: Lead zirconate titanate (PZT)-based piezoelectric ceramics with increasing average grain size were prepared and their properties were systematically investigated. The results showed that the electromechanical properties of the ceramics improved significantly with increasing grain size. In addition, the formation of non-180 degrees domain walls was suppressed in the fine-grain samples, while enhanced domain wall mobility was observed in the coarse-grain samples. This study confirmed that grain size engineering is an effective strategy for designing piezoelectric materials with excellent combination properties.

Summary: The crystallization evolution of lead zirconate titanate (PZT) powders processed from two organic gel systems was investigated, showing that the perovskite PZT form began to crystallize as the calcining temperature reached 400 degrees C and the crystallization mechanism was related to the powder precursor system. The activation energy for perovskite formation was approximately 77 kJ mol(-1) regardless of the precursor system when the Kissinger model was applied.

Summary: The structure of liquid methanol has been investigated using experimental and computational methods. The quasi-crystalline model is applied to analyze the short-range order of methanol, and molecular dynamics simulations are used to obtain the radial distribution functions. The results suggest that methanol at different temperatures and pressures can have different structures, with open chains and cyclic tetramers being the dominant structures at certain conditions.

Summary: A simple modified mixed-oxide reaction method was developed to prepare Dy- and Sm-modified BFPT ceramics with significantly improved properties, showing well-saturated ferroelectric hysteresis loops and enhanced piezoelectric properties suitable for high-temperature applications. The enhanced dielectric/piezoelectric properties were mainly attributed to intrinsic mechanisms of polarization rotation/extension, with minimal extrinsic contributions from interphase and domain walls.

Summary: The behavior of charge density waves (CDWs) in different families of copper-oxide superconductors has been studied. This research found that the CDW amplitude is temperature independent and develops well above experimentally accessible temperatures. The CDW wavevector shows a nonmonotonic temperature dependence, exhibiting different behaviors at low temperatures and near the spin ordering temperature. The study suggests a common mechanism for CDW order in all families of cuprates.

Summary: Lead-free bismuth sodium titanate (BNT) ceramics with a composition of x = 3.5 demonstrate a large strain response of 0.61%. The coexistence of ferroelectric and relaxor domain structures, along with the substitution of antiferroelectric NN, contribute to the enhanced strain response. This study provides new insights into the interplay between mesoscopic domains and macroscopic electrical properties in BNT-based piezoceramics.

Summary: (Na1/2Bi1/2)TiO3-based piezoelectric multilayer actuators (MLAs) have attracted attention as a replacement for lead-based piezoelectric devices due to environmental concerns. In this study, a grain orientation engineering approach was used to prepare a textured NBT-based MLA with high strain output and effective co-firing. The textured MLA achieved a high texturing degree and significantly higher strain performance compared to the non-textured counterpart. The effects of grain orientation engineering on mechanical properties and fracture behavior were analyzed.

Summary: In this study, high-quality PbHfO3 ceramics were prepared via solid-state synthesis and its characteristics were investigated. It was found that PbHfO3 exhibited orthorhombic structure with antiparallel alignment of Pb2+ ions along the [001] directions. The polarization-electric field (P-E) relation of PbHfO3 at room temperature and in the intermediate phase temperature range were measured. The results showed that PbHfO3 had a high recoverable energy-storage density and efficiency at both room temperature and intermediate phase temperature.

Summary: The interplay between magnetism and electronic band topology enriches topological phases and has promising applications. Evidence for topology stabilized magnetism above the magnetic transition temperature in magnetic Weyl semimetal candidate CeAlGe was reported. This indicates the presence of locally correlated magnetism within a narrow temperature window well above the thermodynamic magnetic transition temperature and highlights the role of electronic band topology in stabilizing magnetic order even in the classically disordered regime.

Summary: MnP is a metal that exhibits paramagnetic, ferromagnetic, and helical magnetic phases, and shows superconductivity under high pressure. The magnetic transitions and quantum critical behavior play a crucial role in this material. Through experimental and theoretical calculations, the exchange interactions in the magnetic ground state adjacent to the superconducting phase have been elucidated, which is critical for understanding the pairing mechanism of unconventional superconductivity in MnP.

Summary: The magnetism and dynamics of the cluster glass phase in PbFe1/2Nb1/2O3 (PFN) are investigated using neutron scattering. The cluster glass phase is characterized by the lack of a preferred direction in the average magnetic spin direction and the gradual increase of the magnetic correlation length with decreasing temperature. Below approximately 50K, the spatial correlations become more short ranged, indicating increasing disorder. Neutron spectroscopy reveals fast fluctuations in the cluster glass phase, with a frequency bandwidth that mimics the correlation length. The destruction of magnetic order and the formation of the cluster glass in PFN are attributed to random molecular fields originating from conflicting interactions between clusters.

Summary: In this study, neutron atomic pair distribution function (PDF) analysis was used to investigate the local-structural features of relaxor-ferroelectric materials at low temperatures. The results revealed that the existence of polar nanoregions (PNRs) is characterized by strong displacement correlation rather than structural symmetry. This finding provides a better understanding of the high-performance piezoelectric properties of these materials.
