Description
Resonant inelastic x-ray scattering (RIXS) offers a unique view on local and collective excitations in strongly correlated materials, complementary to established techniques like neutrons, optics, or photoemission. The commissioning at the Swiss Light Source of the high-resolution (E/ΔE~10'000) SAXES soft x-ray spectrometer opened the way to measurements of the full spin wave spectrum in the cuprates, and the accurate evaluation of crucial model parameters. I will discuss RIXS data for the paradigmatic AFM parent compound SrCuO2Cl2 and, for Bi-2212, the evolution of the magnetic excitations into the superconducting part of the phase diagram.
