- W1994168527 abstract "The stability and electronic and magnetic properties of Fe atoms adsorbed on the self-assembled Bi-line nanostructure on the H∕Si(001) surface are addressed by spin-density functional calculations. Our results show that Fe adatoms are much more stable on sites closer to the Bi nanolines suggesting that they form one-dimensional atomic arrays. The most stable structure occurs on a missing dimer line beside the Bi dimers, which corresponds to an array with distances between Fe adatoms of about 8Å. In this array the irons are coupled antiferromagnetically with spin magnetic moment of about 1.5μB per Fe atom, whereas the coupling exchange interactions is found to be of about 14.4meV. We also estimate a large magnetic anisotropy energy of 3meV∕at. originated on the structural anisotropy of the Fe-adatom site. In addition, the electronic band structure of the Fe array at the most stable structure shows a magnetic half-metal behavior." @default.
