“…The straight line labeled F points out the Fermi level. As the annealing temperature increases, peaks P1 and P2 located at 0.9 and 1.6 eV emerge at 410-545 K. According to the UPS studies of Co/Pt(1 1 1) and Ni/Pt(1 1 1) systems, peaks P1 and P2 originate from Co and Ni states on Pt, respectively [11,12]. A change occurred at around 575 K. Peaks P1 and P2 shift slightly forward the Fermi level to 0.8 and 1.4 eV.…”
