We find closed-form solution of the Euler equation for a chiral magnet in terms of a skyrmion or a meron depending on the relative strengths of magnetic anisotropy and magnetic field. We show that the relevant length scales for these solutions primarily depend on the strengths of Dzyaloshinskii-Moriya interaction through its ratios, respectively, with magnetic field and magnetic anisotropy. We thus unambiguously determine the parameter dependencies on the radius of the topological structures…

Interaction between skyrmions and antiskyrmions in a coexisting phase of a Heusler material
Coexisting phases of magnetic skyrmions and antiskyrmions have proposed to exhibit a variety of fascinating properties, owing to interactions between them. The recent discovery of the coexisting
Hydrodynamic model of skyrmions and vorticities in the spin-1 Bose-Einstein condensate in ferromagnetic phase at finite temperatures
Quantum hydrodynamic of skyrmions in spinor ultracold bosons at the finite temperature is described. The limit regime of BEC appearing at the zero temperature is discussed either. The skyrmions are

A numerical simulation of this model with further introduction of magnetic anisotropy and magnetic field predicts many other magnetic structures some of which are already observed in the experiments, and nanoscale skyrmion even at vanishingly small DMI is found for the first time in a model.
Square skyrmion crystal in centrosymmetric itinerant magnets
We theoretically investigate the origin of the square-type skyrmion crystal in centrosymmetric itinerant magnets, motivated by the recent experimental findings in
Dzyaloshinskii–Moriya-like interaction in ferroelectrics and antiferroelectrics
First-principles simulations combined with group theoretical symmetry analysis are demonstrated to demonstrate that electric DMI does exist and has a one-to-one correspondence with its magnetic analogue, but also reveals a physical source for it.

It is found that the skyrmion Hall angle is independent of input current density and the length-scale which determines the radius of a skyrnion, and this property enables us to propose an experimental setup by which the transverse motion of a skating machine can be restricted so that theSkyrmions can only traverse longitudinally.


Enhanced Stability of Skyrmions in Two-Dimensional Chiral Magnets with Rashba Spin-Orbit Coupling
Recent developments have led to an explosion of activity on skyrmions in three-dimensional (3D) chiral magnets. Experiments have directly probed these topological spin textures, revealed their
Theory of antiskyrmions in magnets
It is shown by a numerical simulation of the Landau–Lifshitz–Gilbert equation that pairs of skyrmion and antiskyrmions are created from the helix state as the magnetic field is increased, indicating that the antiskyrsion offers a unique opportunity to study particles and antiparticles in condensed-matter systems.
Micromagnetics of anti-skyrmions in ultrathin films
We present a combined analytical and numerical micromagnetic study of the equilibrium energy, size and shape of anti-skyrmionic magnetic configurations. Anti-skyrmions can be stabilized when the
Skyrmions in chiral magnets with Rashba and Dresselhaus spin-orbit coupling
Skyrmions are topological spin textures of interest for fundamental science and applications. Previous theoretical studies have focused on systems with broken bulk inversion symmetry, where skyrmions
Observation of two independent skyrmion phases in a chiral magnetic material
Magnetic materials can host skyrmions, which are topologically non-trivial spin textures. In chiral magnets with cubic lattice symmetry, all previously observed skyrmion phases require thermal
Antiskyrmions stabilized at interfaces by anisotropic Dzyaloshinskii-Moriya interactions
On the level of micromagnetics, it is rigorously shown that chiral magnets can not only host skyrmions but also antiskyrmion as least energy configurations over all non-trivial homotopy classes.
Transformation between meron and skyrmion topological spin textures in a chiral magnet
Real-space observations of spin textures in a thin plate of the chiral-lattice magnet Co8Zn9Mn3, which exhibits in-plane magnetic anisotropy, demonstrate the rich variety of topological spin textures and their lattice forms and should stimulate further investigation of emergent electromagnetic properties.
Néel-type skyrmion lattice with confined orientation in the polar magnetic semiconductor GaV4S8.
A new Néel-type of SkL describable as a superposition of spin cycloids in contrast to the Bloch-type SkL in chiral magnets described in terms of spin helices is found in the polar magnetic semiconductor GaV4S8 with rhombohedral (C3v) symmetry and easy axis anisotropy.
Real-space observation of a two-dimensional skyrmion crystal
Real-space imaging of a two-dimensional skyrmion lattice in a thin film of Fe0.5Co 0.5Si using Lorentz transmission electron microscopy reveals a controlled nanometre-scale spin topology, which may be useful in observing unconventional magneto-transport effects.
The properties of isolated chiral skyrmions in thin magnetic films
Axisymmetric solitonic states (chiral skyrmions) have been predicted theoretically more than two decades ago. However, until recently they have been observed in a form of skyrmionic condensates
