Orbital magnetoelectric coupling of three dimensional Chern insulators

npj Quantum Materials
Orbital magnetoelectric effect is closely related to the band topology of bulk crystalline insulators. While the half quantized Chern-Simons coupling is well defined only for insulators with zero Chern number, such as three dimensional (3D) axion ...

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.

Differential Tissue‐Coupled Powering for Battery‐Free Injectable Electroceuticals

Advanced Science, EarlyView.
A thread‐like injectable neural stimulator is powered through differential tissue‐coupled powering (DTCP), which harvests RF‐frequency tissue potentials with an elongated receiver while preserving a injectable cross‐section. The system integrates an ASIC, stimulation electrodes, and a portable transmitter, enabling wireless peripheral nerve stimulation,

Modeling temperature dependent exchange bias in systems with magnetoelectric chromia

AIP Advances, 2017
Exchange bias in a magnetoelectric Cr2O3/ferromagnet system at finite temperature, based on the formation of a domain wall in Cr2O3, has been investigated using Monte Carlo simulation.

Probing Type‐II Multiferroicity in Monolayer NiBr2

Advanced Science, EarlyView.
Type‐II multiferroicity is demonstrated in monolayer NiBr2. Scanning tunneling microscopy resolves ferroelectric polarization arising from non‐collinear magnetic order, and reciprocal control with electric and magnetic fields confirms intrinsic magnetoelectric coupling.
