Abstract
We have studied composition of the bulk and surface of the nanocrystalline Fe_72.5Nb_4.5Cu₁Si₁₀B₁₂ alloy prepared from the amorphous one in dependence on gaseous environment during the crystallization annealing. It was found that the mixture of Ar+H₂ causes differences in the phase composition between bulk and surface layer that influences magnetic properties of the whole sample.
