Electric-Anisotropy-Controlled Phase Transitions and Hysteresis in a Ferroelectric/Ferrimagnetic Bilayer with Three-State Ferroelectricity

open access: yesMagnetism
We investigate a ferrimagnetic/ferroelectric bilayer in which a mixed-spin Heisenberg ferrimagnet is coupled to a three-state ferroelectric layer allowing for a nonpolar state.

Solid-State Synapse Based on Magnetoelectrically Coupled Memristor

open access: yesACS Applied Materials & Interfaces, 2018
Brain-inspired computing architectures attempt to emulate the computations performed in the neurons and the synapses in human brain. Memristors with continuously tunable resistances are ideal building blocks for artificial synapses. Through investigating the memristor behaviors in a La0.7Sr0.3MnO3/BaTiO3/La0.7Sr0.3MnO3 multiferroic tunnel junction, it ...

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

open access: yesAdvanced 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

open access: yesAdvanced 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,

Magnetoelectric coupling at multiferroic interfaces

open access: yes, 2010
Materialien, in denen sowohl magnetische als auch ferroelektrische Ordnungsphänomene in der gleichen kristallinen Phase koexistieren, werden als Multiferroika bezeichnet. Darüber hinaus erlaubt die Kristallsymmetrie eines multiferroischen Materials das Auftreten der magnetoelektrischen Kopplung.

Voltage‐Driven Non‐Volatile Interconversion Between Giant Single‐Domain and Multidomain Magnetic States in a Multiferroic Heterostructure

open access: yesAdvanced Science, EarlyView.
Non‐volatile voltage control of magnetic configurations is achieved in a strain‐coupled multiferroic heterostructure. Voltage pulses reversibly interconvert giant single‐domain and multidomain magnetic states, which remain stable at zero applied voltage. ABSTRACT Voltage control of magnetic states in multiferroic heterostructures represents a promising

Magnetoelectric coupling at metal surfaces

open access: yes, 2012
Magnetoelectric coupling (MEC) allows to change the magnetic state by an electric field. In bulk metallic systems any electric field is screened and MEC is not expected. However, the screening charge leads to displacements of the atomic cores in the surface which in turn may modify the magnetic order.

Probing Type‐II Multiferroicity in Monolayer NiBr2

open access: yesAdvanced 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.
