In this work, the two different Ce-based intermetallic compounds CeRh2Si2 and CeCo2P2 have been studied by means of synchrotron radiation spectroscopic (X-ray absorption and photoelectron emission spectroscopy) and resonant inelastic X-ray scattering methods in combination with ab-initio band structure calculations. The measurements allowed for an improved understanding and interpretation of surface sensitive Ce 4f physics by studying distinct surface terminations and their effects, while being combined in the bulk with Co 3d magnetism.
