Further comparison of model predictions with measured Fe-site spin- and charge-density changes in various bcc Fe-based alloys

Previously measured spin- and charge-density changes in bcc iron caused by replacing its atoms by Al, Si, Ge, Sn, V, and Cr are being compared with the two-parameter Miedema model. The fairly good agreement found between the experimental and the model values permits us to separate the direct s-electron charge transfer from the s-d-electron conversion part from the total observed charge-density change. It turns out that for s-p solutes the dominant process in the s-electron redistribution is due to s-d-electron conversion, while for $3d$ solutes the direct s-electron transfer is more important.
