(Color online) Wang-Landau estimates of the DOS for bcc-iron with (color online). The dashed red curve is for four-shell exchange, the green (light solid) curve is the calculated warped DOS for the 10-shell exchange, and the solid black curve is the density of states for the 10-shell exchange estimated with the Wang-Landau method, . The inset highlights the agreement between and the Wang-Landau estimate for a small energy range.
(Color online) Specific heat, C, calculated for density of states presented in Fig. 1.
Exchange interactions in meV for bcc iron. The interactions in the left-hand table are included in the unperturbed Hamiltonian, , and the right-hand table are interactions treated as the perturbation .
