Electronic and atomic structures of ferromagnetic amorphous alloys containing iron as a major component are studied by means of Mossbauer spectroscopy. In accordance with many experimental results, which indicate that short range ordering in the atomic arrangements are considerably developed in the amorphous structure, the Mossbauer spectra of the amorphous alloys can be analyzed with the assumption that the near neighbour configurations are almost the same as those in the crystalline state. Comparing with the ordinary crystalline alloy structures, no essential difference or strangeness in the internal field distribution, isomer shift, quadrupole effect, and defect structures are found, differing from the generally accepted concept of simple random dense packing structure.
