abstract = {Based on first-principles density functional theory
calculations, we explore the electronic and magnetic
properties of experimentally producible sandwiches and
infinite wires made of repeating benzene molecules and
transition-metal atoms of V, Nb, and Ta. We describe the
bonding mechanism in the molecules and in particular
concentrate on the origin of magnetism in these structures.
We find that all the considered systems have sizable
magnetic moments and ferromagnetic spin ordering, with the
single exception of the V(3)Bz(4) molecule. By including the
spin-orbit coupling into our calculations we determine the
easy and hard axes of the magnetic moment, the strength of
the uniaxial magnetic anisotropy energy (MAE), relevant for
the thermal stability of magnetic orientation, and the
change of the electronic structure with respect to the
direction of the magnetic moment, important for
spin-transport properties. While for the V-based compounds
the values of the MAE are only of the order of 0.05-0.5 meV
per metal atom, increasing the spin-orbit strength by
substituting V with heavier Nb and Ta allows one to achieve
an increase in anisotropy values by one to two orders of
magnitude. The rigid stability of magnetism in these
compounds together with the strong ferromagnetic ordering
makes them attractive candidates for spin-polarized
transport applications. For a Nb-benzene infinite wire the
occurrence of ballistic anisotropic magnetoresistance is
demonstrated.},
