FIG. 1.

Model system for the transport calculation of the single-atom magnetic junction. (a) The Ni-Co/Co(111) junction: A Ni tip (green balls) is placed above the Co adatom on the Co(111) surface. (b) The Ni-Ni/Ni(001) junction. The transport is along the Z direction.

FIG. 2.

(a) The spin-dependent conductance of the Ni-Co/Co(111) junction, and (b) the adsorption height of the Co adatom relative to the surface for different tip heights.

FIG. 3.

(a) Conductance of the Co-Co/Co(111), Ni-Ni/Ni(111), and Ni-Ni/Ni(001) junctions, respectively. (b),(c) The spin-up and spin-down conductances of these three junctions and of the Ni-Co/Co(111) junction, respectively.

FIG. 4.

(a) The majority and (b) minority PDOS of the Co adatom in the Co-Co/Co(111) junction and that of the Ni adatom in the Ni-Ni/Ni(111) junction with a tip height of 4.4 Å. (c) The minority s, , and PDOS of the Co adatom in the Co-Co/Co(111) junction with 4.4 Å tip height.
