Skyrmion-skyrmion and skyrmion-edge repulsions in skyrmion-based racetrack memory [PDF]
Scientific Reports, 2015 Magnetic skyrmions are promising for building next-generation magnetic memories and spintronic devices due to their stability, small size and the extremely low currents needed to move them. In particular, skyrmion-based racetrack memory is attractive for information technology, where skyrmions are used to store information as data bits instead of ...

Programmable Topological Magnetic Textures in Above-Room-Temperature 2D Ferromagnet Fe<sub>3</sub>GaTe<sub>2</sub>. [PDF]
Adv Sci (Weinh)This work demonstrates the programmable generation and deterministic modulation of magnetic skyrmion bags with high‐order topological numbers in the above‐room‐temperature 2D ferromagnet Fe3GaTe2 (FGaT) via current‐pulse control. Furthermore, highly efficient electrical manipulation and current‐driven parallel motion of these high‐order topological ...

Skyrmion Bubbles by Design in a Centrosymmetric Kagome Magnet. [PDF]
Adv Sci (Weinh)Chemical tuning of magnetocrystalline anisotropy in the centrosymmetric kagome magnet TmMn6Sn6 is shown to drive a spin reorientation transition via an intermediate magnetic fan state and to stabilize an emergent skyrmion bubble lattice. Four‐dimensional cryogenic Lorentz scanning transmission electron microscopy confirms the nanoscale texture ...

Stripe skyrmions and skyrmion crystals [PDF]
Communications Physics, 2020 Abstract Skyrmions are important in quantum field theory and information technology for being topological solitons and for their attractive applications. Magnetic skyrmions are believed to be circular and stripy spin textures accompanied skyrmion crystals (SkXs) termed spiral/helical/cycloid orders have zero skyrmion number.

Nanofabrication of Topological Surface Relief Structures in Azopolymers With Tightly Focused Optical Skyrmions. [PDF]
NanophotonicsWe demonstrate the nanofabrication of topological surface relief structures (surface reliefs with a shape like a Möbius strip) in azopolymers using longitudinal electric fields and nano‐scale circular polarization defects (C‐point polarization defect) created by tightly focused optical skyrmions.

Skyrmion–skyrmion interaction in a magnetic film [PDF]
Journal of Physics: Condensed Matter, 2020 Abstract Interaction of two skyrmions stabilized by the ferromagnetic exchange, Dzyaloshinskii–Moriya interaction (DMI), and external magnetic field has been studied numerically on a 2D lattice of size large compared to the separation, d , between the skyrmions. We show that
