Current‐Driven Nonreciprocal Response of Nonequilibrium Skyrmions

Advanced Science, Volume 13, Issue 31, 4 June 2026.
A skyrmion holds great promise for spintronic applications owing to its intrinsic topological stability and high mobility under ultra‐low current excitation. Here, by means of in situ electron microscopy, we demonstrate a skyrmion diode effect and the associated current‐driven nonreciprocal skyrmion dynamics in a designed FeGe‐based microdevice.

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 ...

Aluminum‐Substituted Yttrium Iron Garnet Films With Perpendicular Anisotropy Grown on Silicon by Sputtering

Advanced Electronic Materials, Volume 12, Issue 12, 22 June 2026.
Ultrathin Al‐substituted YIG films with perpendicular magnetic anisotropy are sputter‐grown directly on Si/SiOx using an ultrathin AlOx buffer layer. Al diffusion reduces the saturation magnetization and stabilizes PMA via magnetoelastic effects. Pt/Al:YIG bilayers exhibit strong spin Hall magnetoresistance and efficient spin–orbit torque switching ...

Skyrmions

, 2015
<p>Skyrmions are a class of solitons, which are both topologically stable, meaning that their vacuum manifold has a non-trivial π_3 homotopy group, and energetically stable, meaning that they are local minima of the field energy.

Magnetic structure in the two‐dimensional van der Waals ferromagnet Fe3GaTe2

Journal of Applied Crystallography, Volume 59, Issue 3, Page 809-815, June 2026.
High‐quality single crystals of Fe3GaTe2 were grown using the chemical vapour transport method, allowing for a precise determination of their crystal and magnetic structures. A shortening of the Fei–Fei distance enhances the Fe–Fe exchange interaction, providing a microscopic origin for its higher Curie temperature compared with Fe3GeTe2.High‐quality ...

Nanomagnetic skyrmions

, 2012
Magnetic skyrmions and other topologically protected nanostructures are investigated. Since skyrmions are mathematical rather than physical objects, they describe a wide variety of physical systems, from simple magnetic domain walls to complicated ...

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 ...
