Ferroelectric materials have emerged as significant research hotspots within the field of science and engineering, primarily due to their unique electrical properties. However, characteristics these are influenced by various factors, including material composition, microstructure, preparation processes, which introduce considerable randomness uncertainty. Traditional experimental simulation methods often insufficient for capturing complex interactions, thereby hindering prediction...
Layered magnetic materials with nontrivial spin configurations usually emerge novel and transport properties. Herein, we investigate the anisotropy of properties anomalous Hall effect (AHE) in layered itinerant ferromagnetic (FM) monoclinic ${\mathrm{Cr}}_{5}{\mathrm{Te}}_{8}\phantom{\rule{0.28em}{0ex}}(m\text{\ensuremath{-}}{\mathrm{Cr}}_{5}{\mathrm{Te}}_{8})$ single crystal. There are some observations: (1) Based on measurement angular-dependent magnetization $M(\ensuremath{\varphi})$,...

TEM results confirm presence an amorphous phase at grain boundary trace some Ba elements occupying Ca sites crystal lattice. result XPS spectroscopy, Raman electrical test system reveals that addition can effectively reduce oxygen vacancies ceramics improve DC resistivity (in low-temperature region) ferroelectric dielectric samples....
CaBi2Nb2O9 ceramics were fabricated via the solid-state reaction method by addition of B2O3 as a sintering aid at lower temperatures than that prepared without B2O3. Ferroelectricity, piezoelectricity, and resistivity can be still greatly enhanced when temperature is decreased from 1075 °C for to 975 CaBi2Nb2O9–0.25 wt. % The high weak c-axis texture ensure fully polarized in enough electric field. increased spontaneous ferroelectric remanent polarization result significant enhancement...
We report an unambiguous observation of a room temperature (RT) converse magnetoelectric effect (CME) in ternary BiFeO3-based systems near morphotropic phase boundary (MPB). The results situ XRD diffraction at different applied electric fields reveal that the lattice distortion and transitions dominate RT CME samples MPB.

In order to optimize the overall form of electromagnetic scattering in two-dimensional dielectric media, this work offers a frequency-domain boundary element method based on isogeometric analysis. The Isogeometric (IGABEM) is used guarantee geometric correctness during optimization and prevent over-refinement mesh. Non-uniform rational B-splines are discretize integrals model, enabling rapid numerical computation while ensuring high accuracy. Furthermore, as an alternative model for shape...
The effects of quenching on the structural, electrical, dielectric, ferroelectric (FE), and piezoelectric properties are investigated systematically in 0.85BiFe1-xCrxO3-0.15BaTi1-xMnxO3 (0 ≤ x 0.03) ceramics. Optimal piezoelectricity FE Curie temperature obtained through optimized rate temperature. Quenching effect is especially significant for samples near morphotropic phase boundaries (MPB), which can be ascribed to quenching-induced changes ratio (rhombohedral tetragonal phase) domain...
