“Tone‐Arm” Neuromodulation MEMS Microcoil for In Vivo Imaging

Small, EarlyView.
ABSTRACT Implantable neural interfaces have revolutionized neuromodulation by enabling bidirectional communication between neural circuits and external devices. Yet, existing modalities face important challenges in precision, high invasiveness, and compatibility with advanced in vivo imaging systems.

Chiral nature of magnetic monopoles in artificial spin ice

, 2013
Micromagnetic properties of monopoles in artificial kagome spin ice systems are investigated using numerical simulations. We show that micromagnetics brings additional complexity into the physics of these monopoles that is, by essence, absent in spin ...

Photoinduced Picosecond‐Scale Radial Current for Generating and Converting Spin Textures

Nanophotonics, Volume 15, Issue 7, 13 April 2026.
A picosecond‐scale vector electrical current is generated and applied to generate and convert spin textures. Four target quasiparticle types with different topological states are generated with ultrafast speed (< 50 ps). Besides, the controlled transitions between these spin textures are achieved. ABSTRACT Magnetic skyrmions are topologically protected

Operation Regimes and Design Principles of Delta‐E Effect Sensors

Advanced Sensor Research, Volume 5, Issue 4, April 2026.
Delta‐E effect magnetoelectric sensors enable the detection of weak magnetic fields, yet performance optimization remains nontrivial due to coupled magnetic, mechanical, and electronic losses. A systematic study of 24 miniaturized MEMS devices with different geometries reveals three excitation‐dependent regimes: electronic‐noise, magnetic‐noise, and ...

Modeling Liquid‐Mediated Interactions for Close‐to‐Substrate Magnetic Microparticle Transport in Dynamic Magnetic Field Landscapes

Particle &Particle Systems Characterization, Volume 43, Issue 4, April 2026.
The trajectory of a single magnetic particle moving close to a polymer surface in a tailored magnetic field landscape surrounded by a static fluid is quantified using an adjustable simulation model. Varying simulation parameters give insights in key properties of magnetic particle‐based Lab‐on‐a‐chip systems for medical diagnostics.

Fractional Skyrmion Tubes in Chiral‐Interfaced 3D Magnetic Nanowires

Advanced Functional Materials, Volume 36, Issue 20, 9 March 2026.
In chiral 3D helical magnetic nanowires, the coupling between the geometric and magnetic chirality provides a way to create topological spin states like vortex tubes. Here, it is demonstrated how the breaking of this coupling in interfaced 3D nanowires of opposite chirality leads to even more complex topological spin states, such as fractional ...
