The Dzyaloshinskii–Moriya interaction (DMI) has been identified as nontrivial spin textures stabilizer. Here, we report experimental investigations and theoretical understanding of the anomalous transport properties in non-colinear antiferromagnets with typical kagome lattice. The origin of the anomalous transport appears for both perpendicular and parallel to the kagome planes were discussed. The connection among the structure, magnetic and electrical properties is discussed. The competition between the DMI and the exchange interaction can modulate the nontrivial spin textures, further correlate to the transport properties. Our research will provide a promising way of inducing the nontrivial spin textures which related to the topological states.
