Multiscale multimodel simulation of micromagnetic singularities

Simulation multi-échelles et multi-modèles de singularités micromagnétiques D'un point de vu fondamental, la structure micromagnétique d'un point de Bloch est prédite depuis plus de 50 ans, mais représente cependant une singularité topologique dans le cadre de la théorie du micromagnétisme.

Interconnected skyrmions in a nanowire structure: Micromagnetic simulations

Physical Review B
The magnetization dynamics of two skyrmions with antiparallel vortex rotations on a nanowire substrate were investigated using micromagnetic simulations. When positioned in proximity, the skyrmions exhibit attractive interactions that decrease their separation distance.

Inverse Design of Two‐Dimensional Magnonic Crystals via Topology Optimization with Frequency‐Domain Micromagnetics

Small Structures
Magnonic crystals (MCs) offer magnetic platforms for manipulating propagation characteristics of magnons, the quanta of spin waves. Due to the complex relationship between lattice geometry and magnonic band dispersion, establishing general design ...

Micromagnetic simulation of domain wall propagation along meandering magnetic strip with spatially modulated material parameters

AIP Advances, 2017
Feasibility of two-dimensional propagation of the domain wall (DW) was investigated by micromagnetic simulations. Successful bit-by-bit propagation of the DW was demonstrated in a designed meandering magnetic strip with periodic material parameter ...

Parallelisation of micromagnetic simulations

, 2017
The field of paleomagnetism attempts to understand in detail the the processes of the Earth by studying naturally occurring magnetic samples. These samples are quite unlike those fabricated in the laboratory. They have irregular shapes; they have been squeezed and stretched, heated and cooled and subjected to oxidation.
