Dynamics of coupled vortices in layered magnetic nanodots
, 2005 The spin dynamics are calculated for a model system consisting of magnetically soft, layered nanomagnets, in which two ferromagnetic (F) cylindrical dots, each with a magnetic vortex ground state, are separated by a non-magnetic spacer (N).

Multiscale examination of strain effects in Nd-Fe-B permanent magnets
, 2017 We have performed a combined first-principles and micromagnetic study on the strain effects in Nd-Fe-B magnets. First-principles calculations on Nd2Fe14B reveal that the magnetocrystalline anisotropy (K) is insensitive to the deformation along c axis and

Skyrmion quantum diode prototype: bridging micromagnetic simulations and quantum models
npj SpintronicsMagnetic skyrmions are topologically protected spin textures known for their robustness against perturbations. Their topological stability makes them robust information carriers, ideal for tackling a key challenge in quantum computing: creating reliable,

Micromagnetic study of iron nanoparticles: Influence of size and shape
Results in PhysicsWe report computational micromagnetic simulations of iron nanoparticles with cubic and spherical geometries. The simulations were performed using the open source Ubermag package, which integrates the Object Oriented Micromagnetic Framework (OOMMF) as its

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'.

Discretization Anisotropy in Finite Difference Micromagnetic Simulations
IEEE Transactions on MagneticsFinite 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 ...
