Prominent Role of Spin-Orbit Coupling in FeSe Revealed by Inelastic Neutron Scattering

Prominent Role of Spin-Orbit Coupling in FeSe Revealed by Inelastic Neutron Scattering

In most existing theories for iron-based superconductors, spin-orbit coupling (SOC) has been assumed to be insignificant. Here, we use spin-polarized inelastic neutron scattering to show that collective low-energy spin excitations in the orthorhombic (or “nematic”) phase of FeSe possess nearly no in...
