Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns.

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called ...

Many modern technological applications are based on magnetic forces, e.g. to move components in electric vehicles or to store data on hard disks. Yet magnetic fields are also used as sensors to detect ...

Vortex is ubiquitous in nature including spiral arms of galaxy, planet rotation, hurricane (tornado). A vortex is a typical and well-known magnetic domain structure in dimensionally confined ...

A new metasurface lets scientists flip between ultra-stable light vortices, paving the way for tougher, smarter wireless communication.

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, ...

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 ...

New device switches terahertz pulses between electric and magnetic skyrmions On-demand control of stable toroidal vortices lays groundwork for robust wireless data e ...

Analyzing magnetic nanostructures with a high resolution is a test-and-measurement challenge, but it’s important for both advanced physics insight as well as real-world products such as high-density ...
