17. Similar temperature dependence was also observed in the photoemission spectra for the other core levels, Eu 5p, 4d. The results are not shown here.
18. The value is larger than that obtained by XAS. Because the surface sensitivity is higher for the XPS, the obtained value means that the surface region oxidized more than the bulk.
