The antiferromagnetic Weyl semimetal ${\mathrm{Mn}}_{3}\mathrm{Sn}$ has been shown to generate strong intrinsic anomalous Hall effect (AHE) at room temperature, due to large momentum-space Berry curvature from the time-reversal symmetry-breaking electronic bands of the Kagome planes. This prompts us to investigate intrinsic spin Hall effect, a transverse phenomenon with identical origin …
