Magnetism in V/Co(0001) hcp interfaces: Density functional calculations

► DFT determination of the magnetic map of V overlayers, adatoms and V-Co alloys on Co(0001). ► Induced polarization of V is small and limited to a few overlayers. ► The V adatom is preferentially located at hcp site. ► High induced polarization is obtained for V adatoms and V-Co alloys. ► Partial agreement with MEIS and XMCD is obtained.
