Communications Physics, 2023 Efforts to understand skyrmion behaviour often overlook the interaction potentials but these are key to improve predictive modelling. Here, the authors use an Iterative Boltzmann Inversion technique to construct potentials for skyrmion-skyrmion and ...

Journal of Mathematical Physics, 2000 A systematic numerical study of the classical solutions to the combined system consisting of the Georgi–Glashow model and the SO(3) gauged Skyrme model is presented. The gauging of the Skyrme system permits a lower bound on the energy, so that the solutions of the composite system can be topologically stable. The solutions feature some very interesting

Journal of Physics A: Mathematical and Theoretical, 2023 Abstract A new method is introduced to construct approximations to Skyrmions that are explicit rational functions of the spatial Cartesian coordinates. The scheme uses ADHM data of a Yang–Mills instanton to produce a Skyrmion with a baryon number that is equal to the instanton number.

Skyrmion Alignment and Pinning Effects in a Disordered Multi-Phase Skyrmion Material Co8Zn8Mn4 [PDF]
, 2022 Underlying disorder in skyrmion materials may both inhibit and facilitate skyrmion reorientations and changes in topology. The identification of these disorder-induced topologically active regimes is critical to realizing robust skyrmion spintronic ...

Periodically modulated skyrmion strings in Cu2OSeO3
npj Quantum Materials, 2021 Magnetic skyrmions are vortex-like spin textures, which are usually treated as two-dimensional objects. In their lattice state, they form well-ordered, hexagonal structures, which have been studied in great detail.

, 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.

Stabilizing magnetic skyrmions in constricted nanowires
Scientific Reports, 2022 Magnetic skyrmions are topologically-protected chiral nano-scale spin structures that offer low power and high-density functionalities for spintronic devices. They behave as particles that can be moved, created and annihilated. These characteristics make

Size and profile of skyrmions in skyrmion crystals
Communications Physics, 2021 Understanding the parameters which govern the size of a skyrmion are important to gain greater control over their stability and dynamics but the underlying mechanisms differ from individual skyrmions to skyrmion crystals. To this end, using micromagnetic

Spinning Skyrmions and the Skyrme parameters [PDF]
, 2005 The traditional approach to fixing the parameters of the Skyrme model requires the energy of a spinning Skyrmion to reproduce the nucleon and delta masses.

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 ...
