Noncollinear chiral orbitronics

Non-collinear antiferromagnets (NC-AFM) have attracted much attention recently due to the observation of the anomalous Hall effect (AHE) in these materials despite the small magnetic moments present in their unconventional spin structures, in addition to the giant piezomagnetism and a strain-induced anomalous Nernst effect. These fascinating qualities have hints of multiple competing orders that could be harnessed to enable chirality switching and bring these materials ever closer to realistic antiferromagnetic spintronic devices.
