“…Of these two, the peak at lower binding energy (which is the only one observed in the GGG substrate) corresponds well to the position reported for Fe 2 O 3 , Y 2 O 3 , and Y 3 Fe 5 O 12 [31,33,34]. The second peak on the high binding energy side is supposed to be related to the hydroxile group due to surface contamination [31,35].…”

“…In mixed valence compounds such as Fe 3 O 4 , the satellite is usually not prominent due to the superposition of Fe 2+ and Fe 3+ associated satellites. In XPS studies related to thick YIG films, the 3+ satellite is usually observed [7,25,29,31], indicating the domination of Fe 3+ . In the Fe 2p spectra shown in Fig.…”
