Temperature dependence of the resonance and low energy spin excitations in superconducting FeTe${}_{0.6}$Se${}_{0.4}$

We use inelastic neutron scattering to study the temperature dependence of the low-energy spin excitations in single crystals of superconducting FeTe${}_{0.6}$Se${}_{0.4}$ ($T_c=14$ K)…
