Skyrmion quantum diode prototype: bridging micromagnetic simulations and quantum models

npj Spintronics
Magnetic 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 Physics
We 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

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.

Three-dimensional micromagnetic domain structure of MnAs films on GaAs(001): Experimental imaging and simulations

, 2007
The micromagnetic domain structure of MnAs films on GaAs(001) has been systematically investigated by micromagnetic imaging and simulations. The magnetic force microscopy (MFM) contrast resulting from the stray field of the simulated three-dimensional ...

Dynamic susceptibility of modulated magnetic nanowires

AIP Advances, 2019
We have calculated the dynamic susceptibility of modulated permalloy nanowires of 1-µm long and 50 nm diameter using micromagnetic simulations. The resonance modes obtained from these simulations are investigated as functions of both the position of the ...
