, 2015 In this paper, we present a detailed study of Skyrmion-Skyrmion scattering for two B=1 Skyrmions in the attractive channel where we observe two different scattering regimes. For large separation, the scattering can be approximated as interacting dipoles.

Tunable skyrmion–edge interaction in magnetic multilayers by interlayer exchange coupling
AIP Advances, 2022 Magnetic skyrmions are appealing for applications in emerging topological spintronic devices. However, when magnetic skyrmions in a nanowire are driven by an in-plane current, a transverse Magnus force deflects their trajectories from the current ...

Mechanisms for magnetic skyrmion catalysis and topological superconductivity
Physical Review Research, 2023 We propose an alternative route to stabilize magnetic skyrmion textures which does not require Dzyaloshinkii-Moriya interactions, magnetic anisotropy, or an external Zeeman field.

Skyrmion Lattice in a Chiral Magnet [PDF]
Science, 2009 Skyrmions represent topologically stable field configurations with particle-like properties. We used neutron scattering to observe the spontaneous formation of a two-dimensional lattice of skyrmion lines, a type of magnetic vortex, in the chiral itinerant-electron magnet MnSi. The skyrmion lattice stabilizes at the border between paramagnetism and long-

Skyrmion Knots in Frustrated Magnets [PDF]
Physical Review Letters, 2017 A magnetic Skyrmion is a stable two-dimensional nanoparticle describing a localized winding of the magnetization in certain magnetic materials. Skyrmions are the subject of intense experimental and theoretical investigation and have potential technological spintronic applications.

Writing skyrmions with a magnetic dipole [PDF]
Journal of Applied Physics, 2018 We demonstrate numerically, through energy minimization on large spin lattices, that one can write skyrmions in a thin magnetic film with a magnetic dipole of a few tens of nanometer in size. Nucleation of non-chiral skyrmions as well as chiral skyrmions formed by the Dzyaloshinskii-Moriya interaction has been investigated.

Magnetic Skyrmions Under Confinement
Communications in Mathematical Physics, 2023 AbstractWe present a variational treatment of confined magnetic skyrmions in a minimal micromagnetic model of ultrathin ferromagnetic films with interfacial Dzylashinksii-Moriya interaction (DMI) in competition with the exchange energy, with a possible addition of perpendicular magnetic anisotropy. Under Dirichlet boundary conditions that are motivated

The stability of a skyrmion in a nanotube
New Journal of Physics, 2019 We study the stability of a skyrmion in a nanotube by using micromagnetic simulations. We find that skyrmions can exist stably in a nanotube within a moderate magnetic field range when the magnetic field is perpendicular to the center axis of the ...

The spin structures of interlayer coupled magnetic films with opposite chirality
Scientific Reports, 2018 Using Monte-Carlo simulations and micromagnetic simulations, we reveal how the spin structural correlation and the skyrmion dynamics are affected by the interlayer coupling in a chiral magnetic bilayer system, in which the two layers have opposite ...
