(a) The geometry of the contact viewed from the (110) direction. The leads are depicted as dark (blue) rectangles, the cobalt atoms forming the contact are represented by gray (orange) circles, and a denotes the nearest neighbor distance in
the fcc structure. (b) Sketch of the embedded cluster. Dark (blue) circles: selected atoms of the cobalt leads; gray (orange) circles: cobalt atoms in the nanocontact; empty circles: empty spheres around the contact.
