Phase shift in skyrmion crystals [PDF]
Nature Communications, 2021 Skyrmions are a type of topological spin texture, which can exist as both an isolated state, and as a skyrmion crystal. Here, Hayami et al present a theoretical study of phase shifts in skyrmion crystals, showing how such phase shifts can lead to other ...

Size and profile of skyrmions in skyrmion crystals [PDF]
Communications Physics, 2021 Understanding the parameters which govern the size of a skyrmion are important to gain greater control over their stability and dynamics but the underlying mechanisms differ from individual skyrmions to skyrmion crystals. To this end, using micromagnetic

Large anomalous Nernst effect in a skyrmion crystal. [PDF]
Sci Rep, 2016 AbstractThermoelectric properties of a model skyrmion crystal were theoretically investigated and it was found that its large anomalous Hall conductivity, corresponding to large Chern numbers induced by its peculiar spin structure leads to a large transverse thermoelectric voltage through the anomalous Nernst effect.

Ferroaxial Property Under Hybrid Skyrmion Crystals
CrystalsThe ferroaxial moment, a time-reversal-even axial dipole degree of freedom, plays a key role not only in conventional quantum states of matter but also in anomalous off-diagonal cross-correlated responses.

Skyrmion crystals: Dynamics and phase transition [PDF]
AIP Advances, 2018 We study a crystal of skyrmions generated on a square lattice using a ferromagnetic exchange interaction and a Dzyaloshinskii-Moriya interaction between nearest-neighbors under an external magnetic field.

Reorientation Transition Between Square and Hexagonal Skyrmion Lattices near the Saturation into the Homogeneous State in Quasi-Two-Dimensional Chiral Magnets [PDF]
NanomaterialsI revisit the well-known phase transition between the hexagonal skyrmion lattice and the homogeneous state within the phenomenological Dzyaloshinskii theory for chiral magnets, which includes only the exchange, Dzyaloshinskii–Moriya, and Zeeman energy ...

Skyrmion based magnonic crystals [PDF]
Journal of Applied Physics, 2021 Magnonics is now an attractive field which focuses on the dynamic characteristics of magnons, a kind of quasiparticles in magnetic media, and attempts to apply magnons for functional devices. In order to construct magnon-based devices, it is necessary to fabricate materials with specific and tunable magnon bands and bandgaps.

Meron-Mediated Phase Transitions in Quasi-Two-Dimensional Chiral Magnets with Easy-Plane Anisotropy: Successive Transformation of the Hexagonal Skyrmion Lattice into the Square Lattice and into the Tilted FM State [PDF]
NanomaterialsI revisit the well-known structural transition between hexagonal and square skyrmion lattices and subsequent first-order phase transition into the tilted ferromagnetic state as induced by the increasing easy-plane anisotropy in quasi-two-dimensional ...
