Fluid Ferroelectric Filaments

Advanced Science, 2023
AbstractFreestanding slender fluid filaments of room‐temperature ferroelectric nematic liquid crystals are described. They are stabilized either by internal electric fields of bound charges formed due to polarization splay or by external voltage applied between suspending wires.

Edge polarization topology integrated with sliding ferroelectricity in Moiré system

Nature Communications
Van der Waals moiré heterostructure have been found to exhibits a robust interfacial ferroelectricity down to atomic thickness, and discovering and understanding the complex polarization state in moiré systems is of fundamental interest to condensed ...

Omnipolar Magnetic Field Detection by Superlattice‐Based Hall Sensor

Advanced Functional Materials, EarlyView.
Magnetic‐field‐induced electronic switching is demonstrated in unit‐cell‐engineered La0.7Sr0.3MnO3–BiFeO3 superlattices. Distinct substrate terminations modify magnetic and transport properties. Hall resistance measurements show omnipolar, hysteretic anomalous Hall switching above the Curie temperature, arising from Fe─Mn interfacial exchange, enabling

Endowing Ferroelectric Properties of Tetragonal Lysozyme Crystals through C₆₀ Doping

Crystals
The inherent nonpolarity of tetragonal lysozyme crystals excludes a ferroelectricity response. Herein, we present a demonstration of achieving measurable ferroelectricity in tetragonal lysozyme crystals through C60 doping. Ferroelectric characterizations

Spatially Modulated Morphotropic Phase Boundaries in a Compressively Strained Multiferroic Thin Film

Advanced Functional Materials, EarlyView.
ABSTRACT The coexisting rhombohedral‐like (R′, MA) and tetragonal‐like (T′, MC) monoclinic phases in compressively strained bismuth ferrite thin films exhibit exceptional piezoelectric and magnetic properties. While previous studies have largely focused on probing the morphotropic phase boundaries (MPBs) comprising ordered R′/T′ twins, their self ...

Room temperature ferroelectricity in monolayer graphene sandwiched between hexagonal boron nitride

Nature Communications
The ferroelectricity in stacked van der Waals multilayers through interlayer sliding holds great promise for ultrathin high-density memory devices, yet mostly subject to weak polarization and cryogenic operating condition.

Investigation on structural, dielectric and ferroelectric properties of samarium-substituted BiFeO3–PbTiO3 composites [PDF]

Journal of Advanced Dielectrics, 2017
The polycrystalline samples of 0.8BiSmxFe1−xO3–0.2PbTiO3 (x=0.05,0.10,0.15 and 0.20) were prepared by using the conventional solid-state reaction technique and sintered at high temperature (850∘C).
