Resonant inelastic x-ray scattering study of electronic excitations in insulating K${}_{0.83}$Fe${}_{1.53}$Se${}_2$

H. Gretarsson, T. Nomura, I. Jarrige +9

We report an Fe $K$-edge resonant inelastic X-ray scattering (RIXS) study of K${}_{0.83}$Fe${}_{1.53}$Se${}_2$. This material is an insulator, unlike many parent compounds of iron-based…
