Magnetic Field Sensing Based on Magnetoelectric Coupling of Ampere Force Effect With Piezoelectric Effect in Silver/Poly(Vinylidine Fluoride)/Silver Laminated Composite

IEEE Access, 2020
With the advantages of large piezoelectric constant, wide frequency response range and good flexibility, Poly(vinylidine fluoride) (PVDF) is receiving heightened attention as a promising alternative to traditional piezoelectric materials.

Magnetoelectric coupling in self-assembled BiFeO3–CoFe2O4 nanocomposites on (110)-LaAlO3 substrates

APL Materials, 2021
We describe the magnetic domain structures and magnetoelectric coupling in self-assembled BiFeO3–CoFe2O4 (BFO–CFO) nanocomposite thin films grown on (110)-LaAlO3 substrates, consisting of CFO slab-shaped crystals (nanofins) embedded in a BFO matrix.

Multiferroic‐Centric Materials and Systems Engineering for Battery Applications: An Insight Into Mechanisms, Strategies, and Characterizations

Advanced Science, EarlyView.
Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses

Multiferroicity and Magnetoelectric Coupling in TbMnO₃ Thin Films [PDF]

ACS Applied Materials & Interfaces, 2015
In this work, we report the growth and functional characterizations of multiferroic TbMnO3 thin films grown on Nb-doped SrTiO3 (001) substrates using pulsed laser deposition. By performing detailed magnetic and ferroelectric properties measurements, we demonstrate that the multiferroicity of spin origin known in the bulk crystals can be successfully ...

Ferroelectric Catalysts in the Hydrogen Evolution Reaction: A Perspective

Advanced Science, EarlyView.
This perspective summarizes recent advances in ferroelectric (FE) catalysts for the hydrogen evolution reaction (HER). It first introduces HER fundamentals and FE mechanisms, then classifies FE catalysts into single‐phase, single‐atom‐modified, heterostructured, and other engineered types, with representative examples.

Modeling and Characterization of Mechanically Mediated Structure of Terfenol-D, Pb(Zr, Ti)O₃ and Nonmagnetic Flakes

Chemical Engineering Transactions, 2017
The magnetoelectric samples studied were made up of Terfenol-D, Pb(Zr,Ti)O3 and nonmagnetic flakes. The magnetic-mechanical-electric transform originating from the magnetostrictive effect of Terfenol-D caused the magnetoelectric coupling.

Flat Bands Induced by Non‐Collinear Antiferromagnetism in CoBi2Te4

Advanced Science, EarlyView.
Flat bands emerge at the edges of intrinsically non‐collinear antiferromagnetic CoBi2Te4 two‐septuple layers through the interplay of spin–orbit coupling–driven band inversion and non‐collinear antiferromagnetism, uncovering a previously unexplored mechanism for flat‐band formation and opening new opportunities for strongly correlated quantum states ...

Magnetoelectric Nanoparticles Enable Modulation of Cortical Networks by Low‐Intensity Static Magnetic Fields In Vitro

Advanced Science, EarlyView.
Neuromodulation strategies are increasingly needed to stimulate, restore, or replace altered neuronal activity in disease. Cobalt ferrite‐barium titanate (CFO–BTO) magnetoelectric nanoparticles convert low‐intensity static magnetic fields into local electrical modulation of cortical networks.
