摘要
Magnetic Skyrmions Magnetic skyrmions are chiral solitons that possess inherent dynamic modes. During dynamic excitation spin waves are ejected, which interfere to generate a turbulent magnetic sea. In article number 2300416, using small-angle neutron scattering, Dustin A. Gilbert and co-workers measure the structure of the turbulent spin wave sea and find it to be a fractal. The structure of the fractal is determined by features within the skyrmion and skyrmion lattice.
