Antiferromagnetic systems are becoming an appealing alternative for spintronic-based devices due to the more rapid magnetisation dynamics when compared to their ferromagnetic counterparts. Here, using spin dynamic simulations, the authors demonstrate that the motion of domain walls can achieve supermagnonic speeds in an antiferromagnetic system by means of generation of additional domain wall pairs.
