摘要
Structure and growth of monolayer and bilayer films of Mn and CoMn on Cu(0 0 1) are studied by grazing scattering of fast He+ ions and protons. A (quasi-)hexagonal arrangement is observed for the c(8 x 2) Mn monolayer grown at low temperatures (<270 K). Capping of the film by an additional Mn layer results in a complex, layer dependent film structure, whereas capping with Co results in a pseudomorphic square film. At high temperature, the structure of a c(2 x 2) Mn monolayer is in accordance with a buckled CuMn surface alloy. (C) 2003 Published by Elsevier B.V.
