But physicists are now fashioning a new parallel system called spintronics — of which skyrmions are a part — based on the motion of electron spin, that property that makes atoms magnetic (SN Online: 9/26/17).
When the scientists switched on a specially designed magnetic field, the spins arranged into a twisting structure of loops, knotting up into a configuration known as a Shankar skyrmion.
The team showed that a magnetic skyrmion can be created under a nanocontact, in which a spin - polarized current is injected into the magnetic thin film providing a so - called spin torque to its magnetic moments.
In the magnetic vortices — the skyrmions — the «atomic bar magnets» of the iron atoms spin around (orange and green arrows) and have an opposite orientation in their centres (blue arrows).
A skyrmions can also be stabilized by the spinning motion around its own axis, in a way that's similar to how a top stabilizes itself.
Skyrmions, for example, are a kind of nanomagnet, composed of a spin - correlated ensemble of electrons acting as a topological magnet on certain microscopic surfaces.
