Abstract
Femtosecond optical and X-ray measurements show excitation-specific ultrafast relaxation processes in spinel Co3O4 thin films. Upon ligand-to-metal and metal-to-metal charge transfer, the system decays through different energy pathways characterized by different coherent and incoherent responses.
