Phys. Rev. B 80, 014202 (2009) [6 pages]Efficient local atomic packing in metallic glasses and its correlation with glass-forming abilityReceived 29 January 2009; published 15 July 2009 We have probed local atomic structure of Zr-Cu metallic glasses using time-of-flight neutron and synchrotron x-ray diffraction techniques with high resolution. Our results provide evidence for a scheme of efficient local atomic packing where atomic clusters encompass multiple types of atoms in the first coordination shell. We also demonstrate experimental evidence of a strong correlation between the number of unlike atom bonds and the glass-forming ability. Our findings may provide insights into a broad range of scientific problems where efficient space filling by packing spheres is essential. © 2009 The American Physical Society URL:
