A Gauss–Seidel Projection Method for Micromagnetics Simulations [PDF]

Journal of Computational Physics, 2001
The dynamics of the magnetization distribution in a ferromagnetic thin film problem is studied in this paper. The relaxation process of the magnetization distribution in a ferromagnetic material is described by the Landau-Lifshitz equation for the saturation magnetization \(M = M(t)\). On of the main difficulties in micromagnetic simulation is a severe

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 ...

Fidimag – A Finite Difference Atomistic and Micromagnetic Simulation Package [PDF]

Journal of Open Research Software, 2018
Fidimag is an open-source scientific code for the study of magnetic materials at the nano- or micro-scale using either atomistic or finite difference micromagnetic simulations, which are based on solving the Landau-Lifshitz-Gilbert equation. In addition, it implements simple procedures for calculating energy barriers in the magnetisation through ...

Current‐Driven Chirality Detection of Magnetic Textures in Cylindrical Nanowires

Advanced Functional Materials, Volume 36, Issue 91, 12 November 2026.
Current‐assisted anisotropic magnetoresistance measurements in individual Ni/Au cylindrical nanowires enable detection of vortex chirality near Au segments and selective magnetic reversal in defined wire sections at magnetic fields lower than the propagation field. This approach provides a simple, cost‐effective, and non‐invasive method for probing and

Inverse Design of Nanoparticulate Materials

Advanced Materials, Volume 38, Issue 62, 6 November 2026.
Inverse design shifts nanomaterial development from empirical trial‐and‐error to predictive model‐driven strategies. It can rely on knowledge‐based, data‐based, or hybrid process and property functions. This perspective article provides a practical framework for applying inverse design based on instructive examples. It discusses which modeling approach
