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.

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'.

Numerical simulation projects in micromagnetics with Jupyter [PDF]

American Journal of Physics
We report a case study where an existing materials science course was modified to include numerical simulation projects on the micromagnetic behavior of materials. The Ubermag micromagnetic simulation software package is used in order to solve problems computationally.

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.

Accelerate micromagnetic simulations with GPU programming in MATLAB

CoRR, 2015
A finite-difference Micromagnetic simulation code written in MATLAB is presented with Graphics Processing Unit (GPU) acceleration. The high performance of Graphics Processing Unit (GPU) is demonstrated compared to a typical Central Processing Unit (CPU) based code. The speed-up of GPU to CPU is shown to be greater than 30 for problems with larger sizes
