The electronic structure of amorphous and crystalline Fe100–xBx alloys for 14≤x≤19.5 has been studied by x-ray photoelectron spectroscopy and calculated in terms of the modified coherent potential approximation. Exchange splitting measurements of 3s-spectra were used to estimate the atomic magnetic moment of the Fe atom in Fe-B amorphous and crystalline alloys. These results agree qualitatively with saturation magnetization measurements including the deviation from the Slater-Pauling curve. This deviation according to our calculations is the result of the specific charge transfer of s, p and d electrons at about 15.5 at % B. The calculation in ternary alloy approach shows a stable ferromagnetic state of Fe atoms for the studied alloy concentrations.

We elucidate the magnetic properties of amorphous Fe-Ni alloys by combining the geometrical-mean model for the ground-state electronic structure calculations of amorphous alloys with the finite-temperature theory of metallic magnetism. The numerical results show the strong ferromagnetism in the region 0.1≤c≤0.8 and the shift of the Curie-temperature maximum to the higher Fe concentration in agreement with the experimental data. We have clarified that these behaviors are not simply due to the volume change, but due to the change of electronic structure which causes the magnetic energy gain. The agreement between the calculated concentration dependence of effective Bohr magneton number and the experimental data for liquid alloys also supports our theoretical results.
