A new magnetic swirl, or skyrmion, could upgrade data storage
Physicists have now created the tiny whorls in synthetic antiferromagnets

Physicists have created what are known as skyrmions in synthetic antiferromagnets. These atomic whirlpools, in which the tiny magnetic fields of individual atoms arrange into a swirl pattern, could one day be used to store data and create smaller, speedier hard drives.
