Abstract

We present the result of ab initio calculations of the electronic structure for series of Fe100-xBx and Ni100-xBx crystalline and amorphous alloys. DOSs of iron and nickel borides of the same composition have almost the same shapes, rigidly shifted with respect to the Fermi level. This explains the paramagnetic behaviour of nickel diluted by non-magnetic atoms. We traced in detail the effect of amorphisation on the electronic densities of states (DOS). The magnetic moment on the Fe atom gradually decreases with increasing boron content, with more rapid decay in amorphous phase. The calculated electron energy loss spectra (EELS) are practically identical for all iron compounds studied and turned out to be almost insensitive to the ferromagnetic ordering, in accordance with the available experimental data.
