(a) Isotropic FY XAS spectra for the as-deposited (black line) and annealed (red line) Co-doped ITO film. Results recorded at 2 K in an applied magnetic field of 4 T. The arrows indicate spectral features that arise after annealing. (b) XMCD spectra for the as-deposited (black line) and annealed (red line) Co-doped ITO film. The new spectral features for the annealed sample are indicated with red arrows. The spectra have been normalized at edge.
