Figure 4
Total (black solid lines) and partial (dashed coloured lines) DOS for La0.875Ca0.125FeO3 (top) and for La0.5Ca0.5FeO3 (bottom). The dashed vertical lines represent the Fermi levels (set to 0 eV). The total DOS for the undoped bulk is shown as a grey area for reference. The insets show the region around the Fermi level. States above the x axis (positive values) correspond to states of spin-up electrons, while states below the x axis (negative values) correspond to states of spin-down electrons. For Fe3+ and Fe4+ in the lower figure, only one spin is shown and the antiferromagnetic counterparts have been omitted. |
