Abstract ：X-ray magnetic linear dichroism (XMLD) experiments were carried out at beam line 3W1B of the Beijing Synchrotron Radiation Facility. The results demonstrate the experimental XMLD spectra of Co35 Fe65 alloy film annealed with and without oxygen gas, in agreement with the ligand field multiplet calculation. It can be concluded that cobalt atoms are more difficult to oxidize than iron atoms. The oxygen atoms inserting into the sample surface interval lead to the lattice distortion and the fine tuning of the occupation number of absorption atom d -orbits.
