Spin Hall effect in noncollinear kagome antiferromagnets

The spin Hall effect is commonly considered to be related to spin-orbit interaction that causes a deflection of charge carriers according to their spin orientation into opposite directions. Thus, this effect creates spin currents in nonmagnetic materials with spin-orbit coupling. However, recently large spin Hall effects were predicted in coplanar kagome antiferromagnets {\mathrm{Mn}}_{3}\mathrm{X}even when spin-orbit interaction is not...
