NMR and the local structure of relaxors [PDF]
Science of Sintering, 2002 The relaxor transition in cubic perovskite relaxors (PMN, PSN and PST) and tungsten bronze relaxor (SBN) has been studied by NMR. The observed spectra are composed of a narrow -1/2 « 1/2 central transition superimposed on a broad background due to ...

Temperature-dependent energy storage characterization of Pb-free relaxor ferroelectrics [PDF]
Journal of Advanced Dielectrics, 2020 The energy storage properties of (1−x)Bi0.5Na0.5TiO3–xBaTiO3(0≤x≤0.08) (BNT–BT) ceramics obtained via sol–gel method are determined from the polarization versus electric field (P–E) loops at various temperatures. The energy storage densities are observed

Ferroelectricity in Antiferromagnetic Wurtzite Nitrides
Advanced Functional Materials, EarlyView.We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

Advanced Functional Materials, EarlyView.Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...
