High energy X-ray photoelectron spectroscopy (HAXPES) measurements were carried out for the Spin Seebeck system Pt/Y $_{3}$ Fe $_{5}$ O $_{12}$ (YIG). This system was found to show anomalous Hall effect, possible due to the formation of intermetallic compounds between Fe $^{3+}$ and Pt. To reveal this possibility, we have measured the Fe 1s photoelectron peaks by using HAXPES. It was found that the Fe ions consist of Fe $^{3+}$ in YIG and metallic Fe. The formation of the metallic state is consistent with the proposed origin of the anomalous Hall effect. Other spectra such as Pt 4f will be presented at the conference.
