Microstructure of nanocrystalline alloys of Fe_73.5Cu₁Nb₃Si_13.5B₉ and (Fe₃Si)_0.95Nb_0.05 was investigated by Mossbauer spectroscopy. A Nb-rich interfacial layer with weak magnetism formed in the residual amorphous phase of these materials. It has an important effect on the exchange coupling and magnetic properties.
