A new magnetic swirl, or skyrmion, could upgrade data storage

• arclein

Skyrmions previously have been created in materials known as ferromagnets, in which the tiny magnetic field of each atom aligns with its neighbors'. Those aligned fields are the source of ferromagnets' ability to affix kids' doodles to the fridge. But scientists hadn't yet created skyrmions in antiferromagnets, where each atom's magnetic field points opposite to its neighbor's, cancelling out the magnetic field.
