Abstract

Using Mössbauer spectroscopy we have investigated a set of Fe78−xNixSi8B14 amorphous alloys produced by melt spinning. The samples are all ferromagnetic at room temperature even for an iron concentration as low as 20 at. %. The most interesting observation is the evident asymmetry characterizing the Mossbauer fingerprints for x≦38. We suggest that this asymmetry mirros a change of the short range order.
