Skyrmions open a door to next-level data storage
Knots in magnetic materials could one day make for faster, sturdier, tinier electronics
MAGNETIC KNOTS A skyrmion is a swirl (red) among the atoms of a magnetic material. Here, cones point in the direction of each atom’s magnetization. Skyrmions come in several types; this one, a Néel skyrmion, is found in thin materials.
