Our recent AXS experiments on a Gd65Co35 MG demonstrated that small but distinct structural changes were observed even in the first neighbouring shells by the rejuvenation effect with a temperature cycling between liquid N2 and room temperatures [1]. Ketov et al. [2] examined the presence of such an effect in the context of structural and elastic heterogeneities in MGs. Hufnagel [3] suggested that the effect should be caused in the atomistic configurations. We expect to clarify that structural changes universally occur in MGs by the rejuvenation effect, although depending on the extent of structural/elastic heterogeneities.
