Low-energy spin excitations in Li(0.8)Fe(0.2)ODFeSe superconductor studied with inelastic neutron scattering

Mingwei Ma, Lichen Wang, Philippe Bourges +3

We report an inelastic neutron scattering study of single crystals of (Li${}_{0.8}$Fe${}_{0.2}$)ODFeSe. Temperature-dependent low-energy spin excitations are observed near $\mathbf{Q}=…
