Skyrmion size in skyrmion crystals [PDF]

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.

Stripe skyrmions and skyrmion crystals [PDF]

open access: yesCommunications 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.

Multiply periodic states and isolated skyrmions in an anisotropic frustrated magnet [PDF]

open access: yes, 2015
Multiply periodic states appear in a wide variety of physical contexts, such as the Rayleigh-Benard convection, Faraday waves, liquid crystals, domain patterns in ferromagnetic films and skyrmion crystals recently observed in chiral magnets.

CP2 skyrmions and skyrmion crystals in realistic quantum magnets

open access: yesNature Communications, 2023
AbstractMagnetic skyrmions are nanoscale topological textures that have been recently observed in different families of quantum magnets. These objects are called CP1 skyrmions because they are built from dipoles—the target manifold is the 1D complex projective space, CP1 ≅ S2. Here we report the emergence of magnetic CP2 skyrmions in a realistic spin-1

Baby Skyrmion crystals [PDF]

open access: yesPhysical Review D, 2022
This paper describes a model for baby Skyrme crystal chunks with arbitrary potential by considering energy contributions from the bulk and surface of a crystal chunk. We focus on two potentials which yield distinct Skyrme lattices: the standard potential $V=m^2(1- ^3)$ and the easy plane potential $V=\frac{1}{2}m^2 ( ^1)^2$.

Dynamic Susceptibility of Skyrmion Crystal

open access: yesPisʹma v žurnal êksperimentalʹnoj i teoretičeskoj fiziki, 2023
Using stereographic projection approach, we develop a theory for calculation of dynamic susceptibility tensor of Skyrmion crystals (SkX), formed in thin ferromagnetic films with Dzyaloshinskii–Moriya interaction and in the external magnetic field.

Skyrmion Spin Ice in Liquid Crystals [PDF]

open access: yesPhysical Review Letters, 2021
We propose the first Skyrmion Spin Ice, realized via confined, interacting liquid crystal skyrmions. Skyrmions in a chiral nematic liquid crystal behave as quasi-particles that can be dynamically confined, bound, and created or annihilated individually with ease and precision.

Goldstone Mode of Skyrmion Crystal

open access: yesPisʹma v žurnal êksperimentalʹnoj i teoretičeskoj fiziki, 2023
We discuss the Goldstone mode of skyrmion crystal in a model of two-dimensional ferromagnet with the Dzyaloshinskii–Moriya interaction in magnetic field. We use stereographic projection approach to construct skyrmion crystal and consider skyrmion displacement field.

Mechanisms of Skyrmion and Skyrmion Crystal Formation from the Conical Phase [PDF]

open access: yesNano Letters, 2020
Real-space topological magnetic structures such as skyrmions and merons are promising candidates for information storage and transport. However, the microscopic mechanisms that control their formation and evolution are still not clear. Here, using in-situ Lorentz transmission electron microscopy, we demonstrate that skyrmion crystals (SkXs) can ...
