Electrical manipulation of skyrmions in a chiral magnet

open access: yesNature Communications, 2022
There has been much interest in using skyrmions for new approaches to compution, however, creating, deleting and driving skyrmions remains a challenge.

Laser-induced topological spin switching in a 2D van der Waals magnet

open access: yesNature Communications, 2023
Van der Waals magnetic materials, which maintain their magnetic ordering down to a monolayer have been found to host a variety of spin textures, including topological spin textures such as skyrmions. Here, Khela et al.

Real-space observations of 60-nm skyrmion dynamics in an insulating magnet under low heat flow

open access: yesNature Communications, 2021
Skyrmions are a type of topological spin texture that great potential across a wide variety of technological applications. Here, Yu et al. study the thermally driven motion of Skyrmions and find a minimum temperature gradient for the motion of skyrmions ...

Spontaneous Topological States and Their Mutual Transformations in a Rare‐Earth Ferrimagnet

open access: yesAdvanced Science, 2023
Nontrivial chiral spin textures with nanometric sizes and novel characteristics (e.g., magnetic skyrmions) are promising for encoding information bits in future energy‐efficient and high‐density spintronic devices.

Magnetic skyrmion braids [PDF]

open access: yesNature Communications, 2021
AbstractSkyrmions are vortex-like spin textures that form strings in magnetic crystals. Due to the analogy to elastic strings, skyrmion strings are naturally expected to braid and form complex three-dimensional patterns, but this phenomenon has not been explored yet.

Individual skyrmion manipulation by local magnetic field gradients [PDF]

open access: yes, 2019
Magnetic skyrmions are topologically protected spin textures, stabilised in systems with strong Dzyaloshinskii-Moriya interaction (DMI). Several studies have shown that electrical currents can move skyrmions efficiently through spin-orbit torques.

Skyrmion Echo in a System of Interacting Skyrmions

open access: yesPhysical Review Letters, 2022
We consider helical rotation of skyrmions confined in the potentials formed by nano-disks. Based on numerical and analytical calculations we propose the skyrmion echo phenomenon. The physical mechanism of the skyrmion echo formation is also proposed.

Integrability and chemical potential in the (3+1)-dimensional Skyrme model

open access: yesPhysics Letters B, 2017
Using a remarkable mapping from the original (3+1)dimensional Skyrme model to the Sine-Gordon model, we construct the first analytic examples of Skyrmions as well as of Skyrmions–anti-Skyrmions bound states within a finite box in 3+1 dimensional flat ...

Skyrmion size in skyrmion crystals

open access: yes, 2021
A magnetic skyrmion is a topological object that can exist as a solitary embedded in the vast ferromagnetic phase, or coexists with a group of its "siblings" in various stripy phases as well as skyrmion crystals (SkXs). Isolated skyrmions and skyrmions in an SkX are circular while a skyrmion in other phases is a stripe of various forms.
