# Anomalous Hall Effect and Spontaneous Orbital Magnetization in Antiferromagnetic Weyl Metal

@inproceedings{Ito2017AnomalousHE, title={Anomalous Hall Effect and Spontaneous Orbital Magnetization in Antiferromagnetic Weyl Metal}, author={Naohiro Ito and Kentaro Nomura}, year={2017} }

We study the anomalous Hall effect and the orbital magnetization in chiral antiferromagnets, constructing a simple tight-binding model on a stacked Kagome lattice structure with spin-orbit coupling and the exchange interaction between the localized spins and itinerant electrons. It is shown that the chiral antiferromagnet with spin-orbit coupling is an orbital ferromagnet with the easy-plane anisotropy. The relation between the orbital magnetization and the configuration of the Weyl points are…
