Ground-state magnetic structure of Mn3Ge
We have used spherical neutron polarimetry to investigate the magnetic structure of the Mn spins in the hexagonal semimetal Mn3Ge, which exhibits a large intrinsic anomalous Hall effect.

| description | We have used spherical neutron polarimetry to investigate the magnetic structure of the Mn spins in the hexagonal semimetal Mn3Ge, which exhibits a large intrinsic anomalous Hall effect. Our analysis of the polarimetric data finds a strong preference for a spin structure with E1g symmetry relative to the D6h point group. We show that weak ferromagnetism is an inevitable consequence of the symmetry of the observed magnetic structure, and that sixth-order anisotropy is needed to select a unique ground state. |
