The theory of indirect resonant inelastic X-ray scattering on magnons
Recent experiments reveal indirect resonant inelastic X-ray scattering (RIXS) to be a new probe of spin dynamics. Here I derive the cross-section for magnetic RIXS and determine the momentum-dependent four-spin correlation function that it measures. These results show that this technique offers information on spin dynamics that is complementary to, …
