Raman and fluorescence characteristics of resonant inelastic X-ray scattering from doped superconducting cuprates
Raman and fluorescence characteristics of resonant inelastic X-ray scattering from doped superconducting cuprates
Measurements of spin excitations are essential for an understanding of spin-mediated pairing for superconductivity; and resonant inelastic X-ray scattering (RIXS) provides a considerable opportunity to probe high-energy spin excitations. However, whether RIXS correctly measures the collective spin excitations of doped superconducting cuprates remains under debate. Here we demonstrate distinct Raman- …
