Evolution of spin excitations from bulk to monolayer FeSe

Evolution of spin excitations from bulk to monolayer FeSe

Here, Pelliciari et al. present resonant inelastic X-ray scattering on monolayer samples of unconventional superconductor FeSe, finding evidence for gapped and dispersionless spin excitations. These experiments are very difficult due to the extremely small scattering volume of the FeSe monolayer.
