摘要
A systematic study of 3s core-level photoemission spectra of Mn and Fe dihalides shows that exchange splitting, intrashell electron correlation, and final-state screening (charge-transfer satellite) effects all contribute to their satellite structures. It naturally explains both the facts that 3s satellites in MnF2 and FeF2 can be well understood by the exchange-splitting but that 3s splittings in other compounds are not proportional to their magnetic moments in general. We find that only when the charge-transfer satellite in the 2p spectra is negligible does the 3s splitting reflect the local moment of the ground state.
