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'.

Micromagnetic simulations for magnetic multipoles
Applied Physics ReviewsCluster 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.
