Initial growth and coverage determination of Ni ultrathin films on Pt(111)

Finding stabilized coercivity in a study of thickness and temperature dependent Co/Ag/Ge(001) ultrathin films

“…This is consistent with the experimental results for only Co films (the film thickness should be divided a factor 2) on a Ge(001) surface shown in Ref. [10].…”

“…The thickness determination is based on the assumption of an ideal layer-bylayer growth mode. It is also calibrated by measuring the AES elemental signal ratio and by calculations of the adsorbate and substrate signal ratio with the short mean free path of surfacesensitive electrons [10]. The further thickness of Ag and Co layers was determined according to a few layer thickness and then integrating to obtain the extent of thickness.…”

Abnormal reduction of coercivity on magnetic cobalt–platinum alloy films

“…During the deposition, working background pressure did not exceed 2 Â 10 À9 Torr. The relative signal ratios of Ni LMM, Co LMM, and Pt NNV Auger transitions were used to determine the thickness of Ni and Co [9]. The measurements of surface magneto-optical Kerr effect (SMOKE) were carried out in situ by introducing 633 nm He-Ne laser light in and out of the optical view ports.…”

Magnetic properties of ultrathin Co/Ni/Pt(111) films

“…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.…”
