      abstract     = {We report inelastic neutron scattering measurements of
                      low-energy spin fluctuations in FeSe0.95S0.05 (Tc=10 K).
                      Our experiments revealed a resonance mode at 3.5 meV,
                      accompanied by a spin gap below 3 meV at the stripe wave
                      vector in the superconducting state. The resonance mode is
                      sharp in energy and appears at an energy level considerably
                      lower than the superconducting gap, implying that the mode
                      is a bound spin exciton below the superconducting gap rather
                      than an enhanced paramagnon. An abrupt enhancement of stripe
                      spin fluctuations is found below a nematic ordering
                      temperature of Ts=80 K. These results indicate that the
                      direct coupling between the stripe spin fluctuations,
                      nematicity, and superconductivity persists in sulfur doped
                      FeSe, where superconductivity is enhanced and nematicity is
                      partially suppressed.},
