Abstract

The mechanisms of atomic transport in supercooled liquids and the nature of the glass transition are long-standing problems1,2,3,4. Collective atomic motion is thought to play an important role4,5,6 in both phenomena. A metallic supercooled liquid represents an ideal system for studying intrinsic collective motions because of its structural similarity to the “dense random packing of spheres” model7, which is conceptually simple. Unlike polymeric and network glasses, metallic supercooled liquids have only recently become experimentally accessible, following the discovery of bulk metallic glasses8,9,10,11,12. Here we report a 9Be nuclear magnetic resonance study of Zr-based bulk metallic glasses8,9 in which we investigate microscopic transport in supercooled liquids around the glass transition regime. Combining our results with diffusion measurements, we demonstrate that two distinct processes contribute to long-range transport in the supercooled liquid state: single-atom hopping and collective motion, the latter being the dominant process. The effect of the glass transition is clearly visible in the observed diffusion behaviour of the Be atoms.
