“…Ultrathin metallic films epitaxially grown on metallic substrates have been the subjects of many studies because they present very unusual chemical, electronic and magnetic properties, which differ from the corresponding bulk counterparts [276][277][278][279][280][281]. The structure of the grown films is affected by the corresponding substrate with certain crystalline facets [278].…”

“…[33] [278][279][280][281] nearest atoms at neighbor planes and that of the film surface, the total value of elastic energy of the film G e will be larger than the total non-coherent interface free energy G i = Aγ i . Subsequently, the stable strain-free structure with a non-coherent interface is recovered at a critical layer number m c where a transition from the strained structure to a normal one occurs.…”

“…It is interesting that the growth mode of Ni/1 ML Co/ Pt͑111͒ is identical to Ni/ Pt͑111͒ where the growth mode is a layer-by-layer mode, at least for first two monolayers. 11 We found that the magnetic properties of Ni/ Pt͑111͒ have dramatic changes after 1 ML of Co buffer layer was inserted. The MOKE signals of Ni on Pt(111) measured at room temperature are shown in Fig.…”

The growth mode and the structure of ultrathin Ni films on Pt(111) with Co buffer layers were studied by low-energy electron diffraction (LEED) and Auger electron spectroscopy. The comparative study of the magnetic properties between Ni/ Pt͑111͒ and Ni/1 ML Co/ Pt͑111͒ was investigated by magneto-optical Kerr effect. The oscillation of the specular beam of LEED and the Auger uptake curve were used to calibrate the thickness of Ni overlayers and to study the growth mode of Ni thin films on 1 ML Co/ Pt͑111͒. The study of the alloy formation for Ni/1 ML Co/ Pt͑111͒ showed that the temperature for mixing Ni and Co in the upper interface without diffusing into the bulk of Pt is independent of the thickness of Ni overlayers. By further increasing the temperature, Co and Ni diffuse into Pt bulk simultaneously to form Co-Pt, Ni-Pt, and Ni-Co-Pt alloys. The temperature of the formation of these alloys is dependent on the Ni thickness. Studies of the magnetic properties showed that the easy axis of the magnetization changed from the cant to the out-of-plane direction when the Co buffer layer was inserted on Ni/ Pt͑111͒. The alloy formation causes some interesting changes in the polar Kerr signal. The enhancement in the out-of-plane magnetization of Ni/ Co/ Pt͑111͒ is mainly contributed by the formation of Co-Pt alloy.

“…5,6 In the present work, in order to determine the point corresponding to the completion of the first monolayer of Ni deposited on Pt(111), we used a combination of XPS and LEIS. 13 The point at which the Pt signal disappears in the LEIS spectrum was assumed to correspond to the deposition of the first monolayer of Ni.…”

STRUCTURE OF A SINGLE ATOMIC LAYER OF NICKEL DEPOSITED ON THE Pt(111) SURFACE DETERMINED BY LOW ENERGY ELECTRON DIFFRACTION

The structure of ultrathin films of Ni deposited at room temperature on the Pt(111) surface has been determined by low energy electron diffraction (LEED) intensity analysis. The first monolayer of Ni grows pseudomorphically on Pt(111) despite the 11% mismatch between the lattice parameters of nickel and platinum. The results of the analysis also show that the Ni atoms occupy face-centered-cubic sites on the substrate surface. These results in part confirm previous data obtained by X-ray photoelectron diffraction, but also provide more reliable data on the site assignment.
