Abstract
The antiferromagnet Mn${}_{3}$Ge has been recently shown to exhibit a large spontaneous anomalous Hall effect, which can be switched by a small magnetic field and which has been attributed to topologically protected Weyl nodes. Up till now, the true ground-state magnetic structure of the compound has eluded countless experimental studies, which began some fifty years ago. Here, the authors report the use of an advanced polarized neutron scattering technique to resolve unambiguously the magnetic structure of this compound.
