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 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.

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

, 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.

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 ...

Magnetic skyrmion diode: Unidirectional skyrmion motion via symmetry breaking of potential energy barriers [PDF]
, 2021 We realize a magnetic skyrmion diode operated by a unidirectional skyrmion transport that flows in only one direction, which is highly significant for information processing in spintronic and nanoelectronic devices.

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
