Figure 10. Ex-situ perpendicular-mode CW-EPR spectra of LTMO during the processes of (A) Mn oxidation, (B) O oxidation, and (C) reduction. These EPR measurements were performed at 1.8 K. Signal intensities are normalized based on the mass of each material scraped from the electrodes. The sharp signals centered at ~ 345 mT (g ~ 2.0) stem from the delocalized electrons in the conductive carbon black, which can be regarded as an external reference although it may cover up similar signals.
