Abstract
Topological objects interacting with lattice defects are an essential topic in condensed matter physics. This work would like to explore how impurities influence the current-induced dynamics of antiferromagnetic Bimeron (AFM-Bimeron) moving in a racetrack. We investigate three classes of random defects: vacancies, the anisotropy at z-direction like magnetic impurities, and the exchange interaction like a magnetic defect. We have impelled AFM-Bimeron against the impurities region utilizing a spin-polarized current. If the AFM-Bimeron velocity (associated with the strength of the applied current) is high enough, it will pass through the region with the vacancies; else, the defects will destroy the texture. In magnetic impurities, the AFM-Bimeron will pass through the inhomogeneous region without problems, be destroyed, or be deformed, depending on the defects' magnetic parameters.
