Two skyrmions antiferromagnetically coupled: The spin in the centre and the outside spins are antiparallel to each other. Skyrmions in this configuration can be made to diffuse more than 10 times faster than their natural drift rate. (Courtesy: ill./©: Takaaki Dohi/Tohoku University)
Skyrmions – quasiparticles with a vortex-like structure – can be made to diffuse more than 10 ti
