Manipulating 1-dimensional skyrmion motion by the external magnetic field gradient

open access: yesNew Journal of Physics, 2020
We have investigated an approximated analytic form of the one-dimensional motion of skyrmions accelerated by a gradient of the external magnetic field. We find excellent agreement between the analytical calculations and micromagnetic simulations when the

Electrical control of skyrmion density via skyrmion-stripe transformation

open access: yes, 2020
A comprehensive understanding of numerous electrical current-induced magnetic texture transformations is necessary to ensure the reliability of skyrmionic devices during operation.

Skyrmion Lattices in Chiral Metal–organic Frameworks

open access: yes, 2020
Skyrmions are knot-like topologically-protected objects of use in data storage and low-energy smart devices. They can be generated by applying a magnetic field to certain chiral ferromagnets, with the knotted state involving a curling of the underlying ...

Tunable skyrmion–edge interaction in magnetic multilayers by interlayer exchange coupling

open access: yesAIP 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 ...

Icosahedral Skyrmions [PDF]

open access: yesJournal of Mathematical Physics, 2003
In this article we aim to determine the baryon numbers at which the minimal energy Skyrmion has icosahedral symmetry. By comparing polyhedra which arise as minimal energy Skyrmions with the dual of polyhedra that minimize the energy of Coulomb charges on a sphere, we are led to conjecture a sequence of magic baryon numbers, B=7,17,37,67,97,…, at which ...

Skyrmion Dynamics in a Double-Disk Geometry under an Electric Current

open access: yesNanomaterials, 2022
In this work, we present an analysis of skyrmion dynamics considering Dzyaloshinskii–Moriya interactions in an STNO device with a double-disk geometry. Three regimes were observed as a function of geometric parameters and the electric current density: (i)

Shape of a skyrmion [PDF]

open access: yesJournal of Physics: Condensed Matter, 2019
Abstract We propose a method of determining the shape of a two-dimensional magnetic skyrmion, which can be parameterized as the position dependence of the orientation of the local magnetic moment, by using the expansion in terms of the eigenfunctions of the Schrödinger equation of a harmonic oscillator.

No skyrmion hair for stationary spherically symmetric reflecting stars

open access: yesPhysics Letters B, 2019
We investigate the existence of the skyrmion field in the background of an asymptotically flat stationary reflecting star. For this purpose, we consider the Einstein-Skyrme system for which there is a skyrmion hair in the black hole case.
