<abstract xmlns="http://www.w3.org/1999/xhtml">Amorphous precursors of A: (Fe64Co21B15)95P4Cu1 and B: (Fe64Co21B15)96P4 alloys were used. Nanocrystalline structure was created by heat treatment. Samples were studied by Mössbauer spectroscopy, XRD and AFM. Cu ions of dose 1016 at/cm2 were implanted into the amorphous B. According to simulated program we estimated that Cu ions created surface layer with a thickness of a few micrometres. Changes in bulk structure were not observed at parameters of Mössbauer spectra after implantation. After heat treatment the implanted sample was nearly identical with the nanocrystalline sample of A.
