Stray Magnetic Field Variations and Micromagnetic Simulations: Models for Ni_0.8Fe_0.2 Disks Used for Microparticle Trapping [PDF]

Micromachines
Patterned micro-scale thin-film magnetic structures, in conjunction with weak (~few tens of Oe) applied magnetic fields, can create energy landscapes capable of trapping and transporting fluid-borne magnetic microparticles.

Micromagnetic simulations of magnetoelectric materials [PDF]

Journal of Applied Physics, 2011
Some magnetic materials show a magnetoelectric coupling between inhomogeneous magnetization patterns and electric polarization that is sufficiently strong to allow external control of magnetization structure by electric fields. Numerical simulations of “magnetoelectric” materials of this type require an extension of the standard micromagnetic model ...

Strayfield calculation for micromagnetic simulations using true periodic boundary conditions [PDF]

Scientific Reports, 2021
We present methods for calculating the strayfield in finite element and finite difference micromagnetic simulations using true periodic boundary conditions. In contrast to pseudo periodic boundary conditions, which are widely used in micromagnetic codes,

Comparative Modeling of Frequency Mixing Measurements of Magnetic Nanoparticles Using Micromagnetic Simulations and Langevin Theory [PDF]

Nanomaterials, 2021
Dual frequency magnetic excitation of magnetic nanoparticles (MNP) enables enhanced biosensing applications. This was studied from an experimental and theoretical perspective: nonlinear sum-frequency components of MNP exposed to dual-frequency magnetic ...

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 ...

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

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 ...

Reconfigurable Magnetic Nanopore Platform for Selective Trapping [PDF]

Small Science, Volume 6, Issue 9, September 2026.
Reconfigurable magnetic nanopores enable reversible switching between trapping and non‐trapping states by controlling the magnetic configuration around the nanopore. This strategy provides selective localization of magnetic nanoparticles, opening new opportunities for programable nanopore sensing and active single‐particle manipulation.

Discretization anisotropy in micromagnetic simulations

Finite difference based micromagnetic simulations are a powerful tool for the computational investigation of magnetic structures. In this paper, we demonstrate how the discretization of continuous micromagnetic equations introduces a numerical 'discretization anisotropy'.

Light-induced bimerons in a chiral magnet [PDF]

Nature Communications
Controlled generation of topological spin textures, such as merons and their bound state, the bimerons, is essential for advancing spintronic technologies and elucidating soliton physics in condensed matter.
