A self-consistent spin-diffusion model for micromagnetics

Scientific Reports, 2016
We propose a three-dimensional micromagnetic model that dynamically solves the Landau-Lifshitz-Gilbert equation coupled to the full spin-diffusion equation.

Room‐Temperature Skyrmionic Synapse in 2D Ferromagnet Fe3GaTe2 Operating via Collective Spin Texture Transformation

Advanced Materials, Volume 38, Issue 49, 1 September 2026.
We demonstrate a neuromorphic synapse in 2D Fe3GaTe2 flakes. The device operates via a current‐driven transformation from a skyrmion‐lattice to a stripe‐domain state, yielding a linear anomalous Hall resistance response with a tunable slope to enable multiply‐accumulate operations. Simulations confirm its viability in artificial neural networks.

Micromagnetic modelling and multipole expansions from Micromagnetic Tomography

, 2021
Micromagnetic Tomography (MMT) is a technique that combines X-ray micro tomography and scanning magnetometry data to numerically invert the surface magnetic signal for the magnetic potential of individual magnetic grains via their spherical harmonic expansion [1]. The dipole and higher order multipole moment solutions are uniquely determined, which has

Switchable Magnonic Crystals Based on Spin Crossover/CrSBr Heterostructures

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
Multiscale modeling is employed to investigate the functionality of a light‐controlled, tunable magnonic crystal based on spin‐crossover Fe‐pz molecules integrated with a monolayer of CrSBr. Ab initio simulations confirm that the molecules remain functional on the CrSBr surface, while a semiclassical elastic model demonstrates that light‐induced ...

Direct Observation of Propagating Spin Waves in a Spin Hall Nano‐Oscillator

Advanced Materials, Volume 38, Issue 52, 16 September 2026.
By combining frequency injection locking with time‐resolved scanning transmission x‐ray microscopy (TR‐STXM), the authors image the real‐time magnetization dynamics of a spin Hall nano‐oscillator (SHNO) for the first time. Their results reveal richer dynamics than previously reported and challenge existing assumptions regarding the radiation hardness ...

Temporal High-Order Accurate Numerical Scheme for the Landau–Lifshitz–Gilbert Equation

Mathematics
In this paper, a family of temporal high-order accurate numerical schemes for the Landau–Lifshitz–Gilbert (LLG) equation is proposed. The proposed schemes are developed utilizing the Gauss–Legendre quadrature method, enabling them to achieve arbitrary ...

Stochastic Dynamics of Domain Wall on a Racetrack: Impact of Line‐Edge Roughness

physica status solidi (RRL) – Rapid Research Letters, Volume 20, Issue 9, September 2026.
Line‐edge roughness is shown to induce stochastic domain‐wall pinning in ferromagnetic racetracks even in the absence of thermal fluctuations. The resulting depinning probability exhibits a robust sigmoidal current dependence, revealing a physical mechanism for probabilistic domain‐wall dynamics and highlighting the important role of fabrication ...

Proposal for a micromagnetic standard problem for materials with Dzyaloshinskii–Moriya interaction

New Journal of Physics, 2018
Understanding the role of the Dzyaloshinskii–Moriya interaction (DMI) for the formation of helimagnetic order, as well as the emergence of skyrmions in magnetic systems that lack inversion symmetry, has found increasing interest due to the significant ...
