Ni-Zr and Cu-Zr metallic glasses were employed to elucidate characteristics of shortand medium-range structure by neutron diffraction. The pre-peak characteristic of the mediumrange order was clearly observed at Q∼17 nm -1 in the structure factor, S(Q), for the Ni33.3Zr 66.7 metallic glass. The reverse Monte Carlo (RMC) modeling was also carried out for elucidating the characteristics of the structure for the Ni 333Zr667 and Cu33.3Zr66.7 metallic glasses. The characteristic Ni-Ni partial structure factor obtained experimentally was definitely reproduced by the RMC modeling. Moreover, it was found that the first neighbor distributions of the Ni-Ni and Ni-Zr pairs for the Ni33.3Zr66.7 metallic glass were much sharper than those of the Cu-Cu and Cu-Zr pairs for the Cu33.3Zr66.7 metallic glass. The evidence is strongly correlated with the short- and medium-range order of the structure for metallic glasses.
