We investigate ultrafast dynamics of the anomalous Hall effect (AHE) in the topological antiferromagnet Mn 3 Sn with sub-100 fs time resolution. Optical pulse excitations largely …
D0 19-Mn 3 Sn, an antiferromagnet having a non-collinear spin structure in a kagome lattice, has attracted great attention owing to various intriguing properties such as large anomalous …
Antiferromagnetic materials have a vanishingly small net magnetization, which generates weak dipolar fields and makes them robust against external magnetic perturbation and rapid …
Spin–orbit torque (SOT) switching in chiral antiferromagnets, such as D0 19-Mn 3 Sn, has opened prospects in antiferromagnetic spintronics. In this paper, we investigated the critical …
