A micromagnetic study of domain structure modeling [PDF]

, 2008
To develop a mesoscopic model for magnetic-domain behavior, a domain structure model (DSM) was examined and compared with a micromagnetic simulation. The domain structure of this model is given by several domains with uniform magnetization vectors and ...

Decoupled Spin Hall Voltage Readout for Domain‐Wall Synapses in Embedded Neuromorphic Computing

Advanced Intelligent Systems, EarlyView.
Magnetic domain‐wall synapses provide nonvolatile multilevel states with linear, symmetric weight updates, making them attractive for neuromorphic hardware. However, DW MTJ readout has magnetoresistance‐limited dynamic range, while anomalous‐Hall readout suffers from weak voltage output and read/write coupling.

Micromagnetic simulation of non uniform nanodots with perpendicular anisotropy [PDF]

, 2005
Multilayered Pt/[Co/Pt]/sub 5/ films were fabricated into patterned dots with diameters of 120 and 200 nm by laser interference lithography. Anomalous Hall effect (AHE) measurements were used on an array of dots to measure the switching field and the ...

Recent progress of the exchange bias based on 2D van der Waals ferromagnet

InfoScience, EarlyView.
Ultrathin magnetic materials could help make smaller, energy‐efficient memories, but their magnetic states must remain stable and controllable. This review brings together recent research on exchange bias, a magnetic pinning effect in layered materials, and explains how interfaces and electrical, thermal or mechanical controls can tune it, with optical

Template‐free tuning of magnetic nanoparticle self‐assemblies in response to external electric and magnetic fields

Responsive Materials, EarlyView.
Electrostatically charged aerosol magnetic nanoparticles enable template‐free self‐assembly of nanochains with tunable length and spacing by adjusting electric‐to‐magnetic field ratios. Lower electric fields favor the self‐assembly of longer and more spatially separated chains, while higher electric fields promote a uniform nanoparticle deposition and ...
