Large anomalous Hall effect driven by a nonvanishing Berry curvature in the noncolinear antiferromagnet Mn 3 Ge

It is well established that the anomalous Hall effect displayed by a ferromagnet scales with its magnetization. Therefore, an antiferromagnet that has no net magnetization should exhibit no anomalous Hall effect. We show that the noncolinear triangular antiferromagnet Mn3Ge exhibits a large anomalou...
