Through the oxygen exposure experiments on 3d transition metals (Cr, Fe, Co and Ni) and rare earth (Tb), we studied the initial oxidation by means of Auger peak‐to‐peak height (APPH) method. Based on the results obtained, a simple technique using the ratio of APPH was applied to the Auger depth profile analysis of magneto‐optical disk (MOD). It was clearly indicated that the preferential oxidation of Tb occurred only at the lower interface between the TbFeCo and metal‐oxide layers, and this technique can be used to obtain the chemical information about the interface oxidation in Auger depth profiling.
