Phys. Rev. B 79, 113401 (2009) [4 pages]Spin structure of an atomic protrusion: Probing single atoms on cobalt nanoislandsReceived 11 December 2008; published 3 March 2009 Single Ni, Co, and Cu atoms deposited in the center of cobalt nanoislands grown on Cu(111) are investigated by low-temperature scanning tunneling spectroscopy. The surface states of this model magnetic nanolead are unveiled and assigned to arise from atomiclike and surface-induced states by ab initio calculations. Contrary to the first, the second contribution is predicted by calculations to favor a change in sign of the spin polarization with respect to the pristine lead. © 2009 The American Physical Society URL:
