Spin resonance in the superconducting state of Li1−xFexODFe1−ySe observed by neutron spectroscopy

We have performed inelastic neutron-scattering measurements on a powder sample of the superconductor lithium iron selenide hydroxide Li1−xFexODFe1−ySe(x≃0.16,y≃0.02,Tc=41K). The spectrum shows an enhanced intensity below Tc over an energy range of 0.64×2Δ
