Anomalous Hall Effect in antiferromagnets

Seminar / Tuesday, 09.02.2016 10:00 - 11:30

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