Abstract:
Using density functional theory, we have investigated the structural, electronic and magnetic properties of infinitely periodic organometallic vanadium-anthracene ([V(2)Ant](infinity)) and [V(4)(BNAnt)(2)](infinity) (where BNAnt is B-N analogue of anthracene) for their possible application in spintronics. From our calculations, we find that one-dimensional [V(2)Ant](infinity) and [V(4)(BNAnt)(2)](infinity) wires exhibit robust ferromagnetic half-metallic and metallic behavior, respectively. The finite sized V(6)Ant(2) and V(6)(BNAnt)(2) clusters are also found to exhibit efficient spin filter properties when coupled to graphene electrodes on either side.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...
