Abstract

The electronic structure of ion beam mixed Co/Pt multilayered films was investigated using synchrotron-based soft X-ray fluorescence (SXF) and photoemission spectroscopy (PES). Co/Pt multilayered films (eight periods of Co and Pt sublayers) were prepared on Si(100) substrates by alternating electron-beam evaporation followed by ion beam mixing with 80 keV Ar ions under high vacuum. The SXF and PES measurements show that ion beam mixing can change the spectral features of Co 3d valence bands for PES spectra and the emission energies for Co L₃ SXF spectra. The similar valence-band characteristics of IBM CoPt₃ with pure Co and the low emission energy with respect to stable CoPt₃ alloy are correlated with the isolated Co 3d states with a weakened interatomic interaction due to the reduced coordination.
