| dc.description.abstract | The exchange coupling between single
3
d
magnetic adatoms (Cr, Mn, Fe, and Co) adsorbed on a
Cu(001) surface and a Cr STM tip is studied with
ab initio
calculations. We demonstrate that the spin
direction of single adatoms can be controlled by varying the tip-substrate distance, and the sign of the
exchange energy is determined by the competition of the direct and the indirect interactions between the
tip and the adatom. Based on the spin-dependent transport calculations, we find a magnetoresistance of
about 70% at short tip-substrate distances. | en |
