Magnetic Vortices Seen in 3D
Magnetic vortices just tens of nanometers across are like tiny tornadoes frozen in metal. Called skyrmions, they are remarkably stable: hard to destroy but easy to move. That's why engineers see them as ideal 'bits' for future memory — fast, energy-efficient, and resilient.
But until now, no one knew how such a vortex is structured within the material's depth.
