on the surface of zinc oxide nanowires is investigated by carrying out
density-functional calculations with Hubbard <i>
U </i> correction. Geometry optimizations are performed for a number of adatom
configurations, and the adsorption energies and magnetic moments are
calculated. The lowest-energy adatom configuration is thus determined. It is
found that this configuration possess a canted magnetic moment. This means that
the orientation of the magnetic moment vector can be controlled by applying an
external magnetic field. Band structure calculations reveal that the existence
of this intrinsic magnetic moment causes a exchange splitting of the lower
conduction band states. These findings show that the adsorption of bismuth
leads to magnetic functionalization of zinc oxide nanowires. </p> <p> </p>}, number={6}, publisher={Sakarya University}
