Santoni, U.B. Vetrella, G. Celentano, U. Gambardella, A. Mancini] Superconducting MgB2 films were obtained by in-situ annealing of precursor multilayers deposited at low substrate temperature by sputtering from a MgB2 stoichiometric target and by thermal evaporation of pure Mg. After an in-situ annealing at 500-600°C, the films showed a zero resistance critical temperature up to 31K. The as-obtained MgB2 films were investigated by X-ray photoelectron spectroscopy (XPS) and X-ray auger electron spectroscopy (XAES). The electronic structure was studied by monitoring the B 1s, Mg 2p, O 1s core-levels and the Mg KL2L3 Auger line. For comparison, the electronic structure of an MgB2 commercial superconducting sputtering target, of a not-annealed precursor film and of a sample obtained by direct sputtering from the MgB2 target have also been investigated. Electron spectroscopy showed that in the superconducting systems the Mg KL2L3 Auger line kinetic energy position is always higher by about 0.9eV with respect to the energy position of the same Auger line measured in the non-superconducting samples.
