N1 - Funding Information:
The AXS measurements with synchrotron radiation at the Photon Factory of Institute of Materials Structure Science (IMSS) were carried out under the Proposal no. 2000G239. This work was partly supported by the Special Corporation Funds for Promoting Science and Technology on `Nanohetero Metallic Materials Project'. This work was also financially supported by a Grant-in-Aid for Scientific Research on Priority Areas, (B)(2) (no. 12130201) from the Ministry of Education, Culture, Sports, Science and Technology of Japan.

N2 - The atomic structures around Zr and the noble metals M (M = Pd, Pt and Au) were studied by the anomalous X-ray scattering method in amorphous and quasicrystal Zr-based alloys. The prepeak in an energy differential intensity profile at the absorption edge of the M atoms in the amorphous state indicates the presence of a strong chemical short-range order around the M atoms. Coordination numbers and atomic distances were determined in all the samples. The atomic distances of the Zr-M pairs, which are shorter than those calculated from their Gold Schmidt radii, also suggest the existence of strong chemical bonds between them.
