(Color online) (a) XAS/XMCD data measured at the $\text{Co}{L}_{3,2}$ edges of ${\text{Co}}_2\text{FeSi}$. (b) Schematic description of the absorption process emphasizing the different reference energies for the localized and the delocalized $3d$ final-state configurations.Reuse & Permissions

Figure 2

(Color online) (a) Spin-resolved PDOS calculated from the XAS/XMCD data at the $L_3$ edge. Majority PDOS (green circles) and minority PDOS (red bullets) are shown on a positive scale and negative scale, respectively. Full lines indicate deconvoluted data using a Lorentzian function (0.4 eV width). Theoretical data from Ref. 24 are shown as shaded areas. Thin black and gray (blue) lines denote the majority PDOS stemming from the itinerant band with and without consideration of the core-hole effect. (b) Spin-resolved PDOS derived from the $L_2$-edge data and deconvolution with 0.8 eV width. Arrows mark prominent PDOS features.Reuse & Permissions

Figure 3

(Color online) Spin-resolved PDOS calculated from the XAS/XMCD data measured at the $L_3$ edge for samples as indicated in the figure with data representation equal to Fig. 2a. Shadings denote the approximation of the itinerant band. (h) Comparison of the data shown in (f) and (g) on a magnified energy scale.Reuse & Permissions

Figure 4

(Color online) Separation of the minority PDOS maximum and the Fermi energy $E_{v,max}-E_F$ for the indicated Heusler alloys (full symbols) compared with calculations (open symbols) using local-density approximation (LDA) [squares (Ref. 32); triangle (Ref. 33)], $\text{LDA}+U$ [triangles (Ref. 34); circles (Ref. 14)], and $\text{LDA}+\text{DMFT}$ [diamonds (Ref. 35)]. $N_v$ indicates the number of valence electrons per formula unit.Reuse & Permissions
