(color online) as a function of for (a) Zr (Cu/Ni) , (b) Ti₆₀(Cu/Ni)₄₀, and (c) (Cu/Ni) . The circles are the experimental data. The red and blue regions represent the scaled KWW fits of the β-relaxations for M–Cu and M–Ni ( , Ti, and Y), respectively. The grey regions are fits of the α-relaxations.
