Mössbauer spectroscopy was used to get information about the effect of preparation parameters (quenching rate, temperature and time of solution treatment of melt) on the structure of rapidly quenched Fe70Cr10C7P13, Fe79Cr15B15 and Ni8057Fe1P19 amorphous alloys. We have found smaller but measurable thickness dependent changes in the average Mössbauer parameters and in the hyperfine field distribution of Fe70Cr10C7P13 samples than those observed in Fe70Cr10C10P10 amorphous alloys . On the other hand, differences were found in the hyperfine field distribution of very rapidly quenched Fe70Cr10C7P13 alloys with increasing time of solution treatment of melt. Changes in the average parameters and in the quadrupole splitting distribution were also observed with variation of thickness as well as of temperature of melt in the Fe70Cr15B15 and Ni80(Fe)P19 samples, respectively. The finding can be interpreted in terms of changes in the short range order due to different preparation conditions.
