This density of states was calculated using the density functional theory program WIEN2k. Nickel is a ferromagnetic element, therefore a spin-polarized calculation was performed. In the figure above the density of states for spin-up electrons is plotted on the positive axis and the density of states for spin-down electrons on the negative axis. The following parameters were used for the calculation:
Potential: generalized gradient approximation
Seperation Energy: -9.0 Ry
RK_max: 7.00
Number of points in k-space: 1000
Crystal structure: fcc
Lattice constant: 3.52 Å
Muffin tin radius: 1.22 Å
By numerical integration of the Dos for spin-up and spin-down electrons one can determine the magnetization of an element. The magnetization is simply the difference between the spin-up and spin-down electons. In this case the calculated magnetization is: 0.6 bohr magnetons per atom.
In the following table the datapoints of the density of states are given for spin-up and further down for spin-down electrons.
