Local magnetism in a correlated Kagome magnet with massive Dirac Fermions
Abstract
Recent photoemission and scanning tunneling experiments revealed that Fe3Sn2, a strongly-correlated Kagome magnet, features massive Dirac fermions and an intrinsic electronic nematicity. DFT calculations show that the Dirac mass depends significantly on the local magnetic moment. The electronic nematicity also relates to local magnetism through the spin-orbital coupling. Here, we present our small-angle neutron scattering and angle-resolved charge transport results in combination with DFT calculations to characterize the complex role of local magnetism in Fe3Sn2.
