Micromagnetic simulations for magnetic multipoles

Applied Physics Reviews
Cluster magnetic multipoles are order parameters that characterize the symmetry of spin arrangements in magnetic materials. In particular, high-order multipoles play a pivotal role in altermagnets and non-collinear antiferromagnets, where they govern electrical and optical phenomena.

Large-scale micromagnetic simulation of Nd-Fe-B sintered magnets with Dy-rich shell structures

AIP Advances, 2016
Large-scale micromagnetic simulations have been performed using the energy minimization method on a model with structural features similar to those of Dy grain boundary diffusion (GBD)-processed sintered magnets. Coercivity increases as a linear function

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.

Convergence of highly parallel stray field calculation using the fast multipole method on irregular meshes

AIP Advances, 2018
Fast stray field calculation is commonly considered of great importance for micromagnetic simulations, since it is the most time consuming part of the simulation.

Micromagnetic Simulation of the Depinning Field Domain Wall on Symmetric Double Notch Ferromagnetic Wires

In this paper, we investigate the depinning field domain wall on symmetric double notch ferromagnetic wires by means of micromagnetic simulation for Permalloy (Py), Cobalt (Co), and Nickel (Ni) materials.
