Anomalous Hall effect in non-collinear antiferromagnetic antiperovskite Mn${}_3$Ni${}_{1-x}$Cu${}_x$N

Abstract

We report the anomalous Hall effect (AHE) in antiperovskite Mn${}_3$NiN with substantial doping of Cu on the Ni site (i.e. Mn${}_3$Ni${}_{1-x}$Cu${}_x$N), which stabilizes a noncollinear antiferromagnetic (AFM) order compatible with the AHE. Observed on both sintered polycrystalline pieces and single crystalline films, the AHE does not scale with the net magnetization, contrary to the conventional ferromagnetic case. The existence of the AHE is explained through symmetry analysis based on the ${\Gamma }_{4g}$ AFM order in Cu doped Mn${}_3$NiN. DFT calculations of the intrinsic contribution to the AHE reveal the non-vanishing Berry curvature in momentum space due to the noncollinear magnetic order. Combined with other attractive properties, antiperovskite Mn${}_3$AN system offers great potential in AFM spintronics.
