Antiferromagnetic bimeron shows chaotic behaviors

Magnetic bimeron is a topological spin texture with particle-like characteristics, which can exist in chiral magnets with in-plane magnetic anisotropy. The magnetic bimeron with topological charge of one can be regarded as a counterpart of the magnetic skyrmion in perpendicularly magnetized systems. So far, the studies on magnetic bimerons focus on the ferromagnetic systems. The dynamics of the bimeron in antiferromagnets still remain elusive.
