    • Switching a single spin on metal surfaces: ab initio studies 

      RUNGGER, IVAN; SANVITO, STEFANO (2009)
      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 ...
