Antiferromagnetic skyrmions moved in a magnetic racetrack by an electrical existing. Anticipated as future bits in computer system memory, these nanobubbles use boosted opportunities for details processing in electronic devices. A skyrmion consists of primary nanomagnets (” spins”) that wind to form an extremely steady spiral structure, like a tight knot.The size of a skyrmion can reach a couple of nanometres, which is to state approximately a dozen atoms.Antiferromagnetic stacks consist of two nano-sized ferromagnetic layers (such as cobalt) separated by a think non-magnetic layer, with opposite magnetisation.The SPIN Priority Research Programme and equipment (PEPR) is an exploratory program in connection with the France 2030 investment plan.Reference: “Fast current-induced skyrmion motion in artificial antiferromagnets” by Van Tuong Pham, Naveen Sisodia, Ilaria Di Manici, Joseba Urrestarazu-Larrañaga, Kaushik Bairagi, Johan Pelloux-Prayer, Rodrigo Guedas, Liliana D.
