Micromagnetic Simulation of Nanoscale Films with Perpendicular Anisotropy

, 1996
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

Fully micromagnetic analysis of voltage-controlled magnetization switching in magnetic-topological-insulator-based devices

AIP Advances
We numerically investigate magnetization switching behavior in voltage-controlled magnetic-topological-insulator-based (VC-MTI) devices by means of the fully micromagnetic simulation.

Overcoming thermal noise in non-volatile spin wave logic

, 2017
Spin waves are propagating disturbances in magnetically ordered materials, analogous to lattice waves in solid systems and are often described from a quasiparticle point of view as magnons.

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'.

On the relaxation time of interacting superparamagnetic nanoparticles and implications for magnetic fluid hyperthermia

Beilstein Journal of Nanotechnology, 2019
A critical discussion on the presently available models for the relaxation time of magnetic nanoparticles approaching the superparamagnetic regime in the presence of interparticle dipolar interactions is considered.

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.

Discretization Anisotropy in Finite Difference Micromagnetic Simulations

IEEE Transactions on Magnetics
Finite difference-based micromagnetic simulations are a powerful tool for the computational investigation of magnetic structures. In this article, we demonstrate how the discretization of continuous micromagnetic equations introduces a numerical “discretization anisotropy.” We demonstrate that, in certain scenarios, this anisotropy operates on an ...
