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 ...

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.

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 uncovered a new way to generate exotic oscillation states in tiny magnetic structures—using only minimal energy. By exciting magnetic waves, they triggered a delicate motion that ...

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 ...

Pinning at local defects is a significant road block for the successful implementation of technological paradigms which rely on the dynamic properties of non-trivial magnetic textures. Here, a ...

The electron spins in a magnetic vortex all point in parallel, either clockwise or counterclockwise. Spins in the crowded core of the vortex must point out of the plane, either up or down. The four ...

Controlling this state paves the way for the creation of more intelligent, reconfigurable and energy-efficient devices that mimic the brain. The use of Big Data has multiplied the energy demand in ...

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 ...
