Figure 1
The Compton profiles of the valence electrons in the ferromagnetic state of Fe0.942Si0.058, measured along the [100] direction (a), along the [111] direction (b), and the difference of the two profiles (c). The full lines are corresponding theoretical profiles of pure Fe computed by Kubo & Asano (1990) using the FLAPW method. The theoretical profiles are convoluted with the present experimental resolution of 0.15 a.u. The area under the experimental profiles is normalized to 7.7 electrons/atom, and that of the theoretical profiles gives 7.9 electrons/atom. |
