(a) Selection of intensity correlation functions measured at different temperatures (see legend) in the metallic glass Pd42.5Cu30Ni7.5P20 at q = (28.7 ± 0.4) nm−1. All the measured curves exhibit a stationary dynamics and a shape parameter γ < 1. (b) The average relaxation time is reported as a function of the inverse temperature scaled to the glass transition temperature, Tg. In the temperature range investigated here, the data can be described by a simple exponential behavior (Arrhenius-like dependence, gray dashed line). |
