Abstract
The (110) surface structure of the Pt 25Co 75 alloy in the substitutionally disordered state was studied by quantitative LEED. In a way similar to Pt x Ni 1− x (110) surfaces, on the Ni rich side, the composition profile versus depth is strongly oscillating with a pure cobalt top layer; however, the oscillation is stronger and goes deeper for Pt 25Co 75(110) than for the previously studied surfaces of Pt 10Ni 90(110) and Pt 50Ni 50(110). Actually the selvedge, which can be easily produced by simple standard argon cleaning and annealing UHV techniques, is a sequence of three almost pure layers: CoPtCo. This provides an interesting system to be studied: the monolayer limit of PtCo sandwiches.
