Abstract
Applications in spintronics require components that create or preserve pure spin currents. The authors' calculations show that a nanowire built from organometallic (\ensuremath{\eta}${}^{5}$- C${}_{5}$H${}_{5}$)Ti(\ensuremath{\eta}${}^{8}$-C${}_{8}$H${}_{8}$)Ti clusters is half-metallic, with 100% spin polarization near the Fermi level in its electronic structure. They predict that such a wire coupled to gold electrodes should be multifunctional, which seems quite promising for devices---especially considering that these clusters can actually be prepared in the laboratory.
