Abstract
The structure of various Co/Au(111) multilayers has been investigated, using electron diffraction and high resolution electron microscopy (HREM). The multilayers were grown by electron beam evaporation on a float glass substrate. The cobalt layers exhibit a face centred cubic (f.c.c.) structure with the cobalt [111] axis parallel to the gold [111] axis. For cobalt layers, this f.c.c. structure hadn't been observed in Co/Au multilayers before. Measurements were done on digitized electron diffraction patterns and high resolution images. An important volume expansion of the cobalt lattice and good epitaxial relations between cobalt and gold were observed.
