EPITAXIAL-GROWTH OF PLATINUM ON CO(10.0)

The formation of the interface obtained by deposition of Pt on Co(10.0) has been studied by AES, LEED, and XPS. At room temperature the growth mode is nearly layer-by-layer with a progressive loss of the structural order. Annealing at T less-than-or-equal-to 370-degrees-C of RT deposits or deposition at higher temperatures (T less-than-or-equal-to 300-degrees-C) lead to a better crystallographic structure. In this latter case, after the building of a diffuse zone, the growth is again a layer-by-layer one. In all cases, and particularly at RT, it is possible to grow sandwiches Co/Pt/Co(10.0) with a reasonably good crystallographic structure, opening the possibility to build up superlattices.
