The common notion that the anomalous Hall effect (AHE) is propor-
tional to magnetisation M suggests that antiferromagnets with M = 0
should exhibit no AHE. Despite this intuition, when certain symmetries
are broken, AHE was still predicted to appear in multi-sublattice
antiferromagnets with M = 0 (such as IrMn3 or Mn3Sn). Re-
cently, this prediction has been confirmed experimentally and the
magnitude of AHE was even found to exceed that of ordinary
ferromagnetic metals.
