Skyrmions are microscopic magnetic vortices that can form in certain materials. First detected in 2009, they are of interest to research because they could be harnessed for new forms of data storage.

Researchers used a nonlinear metasurface to experimentally demonstrate skyrmions that can be switched between electric and magnetic modes in free-space toroidal terahertz light pulses. WASHINGTON — ...

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 ...
