Compared with the chiral spin textures in ferromagnets, their antiferromagnetic counterparts can be manipulated by spin currents with a more direct approach due to the absence of the skyrmion Hall effect, and much lower power consumption, as well. So far, most research has focused on isolated excitation in perpendicular antiferromagnetic spin systems, for example, skyrmion solitons. Meanwhile, the characteristics and the related physics of its in-plane analog, the bimeron, remain elusive.
