Spintronics are devices that operate leveraging the spin, an intrinsic form of angular momentum, of electrons. The ability to switch magnetic states is central to the functioning of these devices, as ...

Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns. These structured light vortices, known as skyrmions, are highly stable and ...

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have uncovered previously unobserved oscillation states—so-called Floquet states—in tiny magnetic vortices. Unlike earlier experiments, ...

Artistic illustration of Floquet-engineered magnons: Using time as a resource, a static magnetic vortex evolves into a periodically driven state whose gyration generates a magnon frequency comb.

Magnetic vortices arise in nanoscale ferromagnetic elements when spins curl in-plane around a small, perpendicularly magnetised core. The resulting topological structure exhibits a gyrotropic mode in ...

On-demand control of stable toroidal vortices lays groundwork for robust wireless data encoding. (Nanowerk News) Researchers have created an optical device that can generate both electric and magnetic ...

Just as electrons flow through an electrical conductor, magnetic excitations can travel through certain materials. Such excitations, known in physics as 'magnons' in analogy to the electron, could ...
