Non-coplanar Magnetism in Mn<sub>3</sub>Sn

ORAL

Abstract

The magnetization-free anomalous Hall effect of Mn3Sn yields topological non-trivial bands with Weyl nodes at the Fermi level. Yet the knowledge of its incommensurate phase remains insufficient. Considering incommensurate magnetism itself historically manifests strong electron correlations in unconventional superconductors and heavy fermion systems, studies on the incommensurate magnetism of Mn3Sn provides further insights of the itinerate electrons in Mn3Sn. With neutron scattering techniques, we were able to fully determine the incommensurate magnetic structure and analyze its dynamics. Our results show potential strong correlation and competing interactions in the magnetic Weyl semimetal Mn3Sn.
