Vector‐Field Control and Emergent Basal‐Plane Anisotropy of Magnetic Textures in Noncentrosymmetric (Fe0.63Ni0.3Pd0.07)3P

Advanced Functional Materials, Volume 36, Issue 79, 1 October 2026.
A field‐driven transition from chiral stripes to an achiral fan state is observed in a tetragonal magnet and linked to a temperature‐dependent rotation of the effective Dzyaloshinskii–Moriya interaction axis. This interplay generates pronounced in‐plane anisotropy and provides a new route for controlling chiral spin textures in noncentrosymmetric ...

Topological Spin‐Texture Transitions in van der Waals Magnets Revealed by X‐Ray Fourier Transform Holography

Advanced Materials, Volume 38, Issue 60, 27 October 2026.
Applied here for the first time to a 2D material, high‐resolution synchrotron x‐ray Fourier transform holography directly images topological spin textures in Fe3GeTe2. Combined with atomistic tight‐binding simulations including itinerant electrons and Rashba spin‐orbit coupling, the approach reveals labyrinth, skyrmion, and mixed phases, and uncovers ...

Discretization Anisotropy in Finite Difference Micromagnetic Simulations [PDF]

IEEE Transactions on Magnetics
Finite difference-based micromagnetic simulations are a powerful tool for the computational investigation of magnetic structures. In this article, we demonstrate how the discretization of continuous micromagnetic equations introduces a numerical “discretization anisotropy.” We demonstrate that, in certain scenarios, this anisotropy operates on an ...

Magnetic domain walls interacting with dislocations in micromagnetic simulations

Communications Materials
Defects, impurities, and embedded particles in ferromagnetic materials are long known to be responsible for the Barkhausen effect due to the jerky field-driven motion of domain walls and have more recently been shown to play a role also in domain wall ...

Magnetization dynamics of magnetic domain wall imprinted magnetic films

New Journal of Physics, 2014
The influence of micromagnetic objects on the dynamic magnetic excitation in magnetic thin films is studied by imprinting periodic domain wall patterns through selective ion irradiation in exchange biased Ni _81 Fe _19 /IrMn structures.

Micro-magnetic simulations of correlated switching in touching circular nano-magnetic elements

AIP Advances, 2020
Past studies have demonstrated that logic states can be represented using the rotation of the magnetization at flux-closed remanence in individual ferromagnetic disks.

On the Travelling Wave Solution for the Current-Driven Steady Domain Wall Motion in Magnetic Nanostrips under the Influence of Rashba Field

Advances in Condensed Matter Physics, 2012
Spin-orbit Rashba effect applies a torque on the magnetization of a ferromagnetic nanostrip in the case of structural inversion asymmetry, also affecting the steady domain wall motion induced by a spin-polarized current.

Towards Miniaturization of Magnetic Gears: Torque Performance Assessment

Micromachines, 2017
Magnetomechanical components can be a good solution in order to reduce, or even completely avoid, friction phenomena in micro-electro-mechanical systems (MEMS) since they can transmit forces through magnetic fields without contacts. In this communication,

Micromagnetic simulation of nanoscale films with perpendicular anisotropy [PDF]

Journal of Applied Physics, 1997
A model is studied for the theoretical description of nanoscale magnetic films with high perpendicular anisotropy. In the model, the magnetic film is described in terms of single domain magnetic grains with Ising-like behavior, interacting via exchange as well as via dipolar forces.
