Mg_xPd_100-x (x=70, 80, 85 and 90) amorphous alloys were prepared by the single-roller melt-spinning technique and X-ray diffractometry was performed with synchrotron radiation using the large Debye-Scherrer camera installed at SPring-8. As a result, it has been shown that a medium-range order (MRO) exists in each of the amorphous alloys and that the MRO decreases monotonously with increasing the Mg content. Additionally, it has also been shown that the atomic distances of first neighbor pairs hardly vary although the rate of the coordination numbers varies monotonously with the alloy composition.
