Abstract

The criticisms of Harvey and Gheribi (HG) are directed towards supporting evidence for ordering in supercooled Cu $_{46}$ Zr $_{54}$ liquid from specific heat measurements and molecular dynamics simulations, not on the direct evidence that came from x-ray diffraction studies. In this reply, we demonstrate that the unique features observed in the specific heat [Cp(T)] are not artifacts of any specific assumptions, as suggested by HG. We have furnished additional details of the MD simulations and clarified related issues raised by HG. The basic conclusions, however, remain unchanged.
