- W2038398418 abstract "Our ab initio study explains recent puzzling experiments on the conductance of a single Co adatom deposited either on Cu(111) or on ferromagnetic Co islands and contacted with both magnetic and nonmagnetic electrodes [N. N'eel, J. Kroger, and R. Berndt, Phys. Rev. Lett. 102, 086805 (2009)]. We provide clear evidence that the conductance of a single atomic junction in the contact regime is close to ${G}_{0}/2$ (${G}_{0}$ is the quantum of conductance) for ferromagnetic electrodes and to ${G}_{0}$ for nonmagnetic ones. Spin-dependent calculations reveal that a conductance of ${G}_{0}/2$ originates from a combination of partially open majority and minority channels. The bonding between the Co adatom and the Co island reduces significantly the contribution of the minority $d$ electrons to the conductance, leading to the observation of half-integer conductance." @default.
