Structural and magnetic investigations of the Weyl semimetal family CeAlSi1–xGex

Acta Crystallographica Section B, Volume 82, Issue 3, Page 250-257, June 2026.
A systematic investigation is reported of the structural and magnetic evolution in the CeAlSi1–xGex series, combining X‐ray and neutron diffraction with magnetization measurements on polycrystalline samples and single crystals. Chemical substitution leads to a continuous lattice expansion and a suppression of the ferromagnetic ordering temperature ...

Optical Skyrmions Modulation Based on Polarization Helicity

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
The polarization helicity represents the global twisted property of the polarization state distribution, it can be used to modulate the spin skyrmion texture in the tight focusing of the radially polarized vortex light. By adjusting the polarization helicity of incident field, the Néel‐Bloch‐Néel transition of the spin skyrmion texture can be realized,

Geometry of Skyrmions

Communications in Mathematical Physics, 1987
A Skyrmion is a classical static field configuration of minimal energy in a nonlinear scalar field theory, where the Skyrmion represents a baryon and the scalar field is given by the pion. Mathematically a Skyrmion can be regarded as a topological non-trivial map from one Riemannian manifold to another (3-dimensional, orientable, connected), and the ...

Quantum Dynamics of Skyrmions in Chiral Magnets

Physical Review X, 2017
We study the quantum propagation of a Skyrmion in chiral magnetic insulators by generalizing the micromagnetic equations of motion to a finite-temperature path integral formalism, using field theoretic tools.

Edge-mediated skyrmion chain and its collective dynamics in a confined geometry

, 2015
The emergence of a topologically nontrivial vortex-like magnetic structure, the magnetic skyrmion, has launched new concepts for memory devices. Extensive studies have theoretically demonstrated the ability to encode information bits by using a chain of ...

Electronic Noise of a Single Skyrmion

, 2023
To enable the practical use of skyrmion-based devices, it is essential to achieve a balance between energy efficiency and thermal stability, while also ensuring reliable electrical detection against noise.

Skyrmion Crystal in Bilinear–Biquadratic–Bicubic Model on a Centrosymmetric Triangular Lattice

Condensed Matter
We numerically investigate the effect of multi-spin interactions on the stability of skyrmion crystals and other multiple-Q magnetic states, with a particular emphasis on the momentum-resolved bicubic interaction. By performing simulated annealing for an

Wiggling skyrmion propagation under parametric pumping

, 2019
Magnetic skyrmion motion under parametric pumping is numerically investigated. Parametric pumping with a perpendicularly oscillating electric field can excite the breathing modes of a skyrmion because an electric field can modify the magnetic anisotropy.
