M-H curves of the samples and XPS spectra of S700. (a) Magnetic hysteresis loops of the samples (inset: the initial magnetization curves), (b) XPS survey spectrum of sample S700, and (c) fitted XPS spectra of O 1s of sample S700. The vertical axis represents the signal intensity. KCPS, kilo counts per second; B.E., binding energy.
