Tight-Binding parameters for Cobalt

Cobalt (Co)
Atomic Number	27
Atomic Weight	58.9332
Room Temperature Structure	hcp (A3)
Room Temperature Lattice Constant a	0.251 nm
Room Temperature Lattice Constant c	0.407 nm

We now have parameter sets for both

Paramagnetic Cobalt (co_para_par) and
Ferromagnetic Cobalt (co_ferro_par).

These use the same hopping parameters for spin up, spin down, and the paramagnetic case.

Originally we only provided parameters for the paramagnetic case:

The tight-binding parameters were fit to first-principles spin restricted (spin up density = spin down on each atom) Augmented Plane Wave (APW) results over the following ranges:

Structure	Minimum Lattice Constant (Bohr)	Maximum Lattice Constant (Bohr)
fcc (A1)	6.25	6.65
bcc (A2)	4.80	5.40
Reference	Phys. Rev. B 54, 4519-30 (1996)

Use of the parameters outside of these ranges may result in unphysical behavior.
