Seven supercells, Fe80 (black), Fe78Mg1 (red), Fe78Mg2 (blue), Fe78Mg3 (yellow), Fe78Mg4 (cyan), Fe78Mg6 (magenta), and Fe78Mg8 (green), were investigated. The equations of state are plotted along different isotherms of 6000 K (a), 6500 K (b), 7000 K (c), and 7500 K (d). The fitting parameters are listed in Supplementary Table S1.
