Bartsch et al. [A. Bartsch, K. Raetzke, A. Meyer, and F. Faupel, Phys. Rev.Lett. 104, 195901 (2010)] reported measurements of the diffusivities ofdifferent components of the multi-component bulk metallic glassPd43Cu27Ni10P20. The diffusion of the largest Pd and the smallest P were foundto be drastically different. The Stokes-Einstein relation breaks down whenconsidering the P constituent atom, while the relation is obeyed by the Pd atomover 14 orders of magnitude of change in Pd diffusivity. This difference inbehavior of Pd and P poses a problem challenging for explanation. With theassist of a recent finding in metallic glasses that the beta-relaxation and thediffusion of the smallest component are closely related processes by Yu et al.[H. B. Yu, K. Samwer, Y. Wu, and W. H. Wang, Phys. Rev. Lett. 109, 095508(2012)], we use the Coupling Model (CM) to explain the observed differencebetween P and Pd quantitatively. The same model also explains the correlationbetween property of the beta-relaxation with fragility found in the family of(CexLa1-x)68Al10Cu20Co2.
