| Abstract: | Disorder effects in amorphous Ni66Y33 and Cu60Zr40 alloys have been investigated by the EXAFS technique. EXAFS spectra have been fitted using a double pair distribution function for the TM-TM (transition metal) pairs and for the unlike atom pairs. Both alloys have been found to be chemically ordered. For Cu60Zr40 the amorphous structure is very similar to the crystalline one. |
