Fig. 2. The structural evolution of the as-prepared Ce₆₅Al₁₀Co₂₅ MG at high temperatures.

a S(q) and b G(r) at representative temperatures. More features emerged in the patterns indicate that more ordered states were obtained during heating, but no sharp Bragg diffraction peaks were observed. c Representative SAXS data in the ordering temperature range, data at 300 K are also shown for comparison. The initial sample at 300 K is homogeneous according to its monotonically decayed data, whereas a hump at ~ 0.08 Å is observed when ordering starts above 427 K, implying density fluctuation emerges. d The comparison of Porod invariant at 427 K and 475 K relative to the value at room temperature, implying a considerable increasing of the volume of the heterogeneous scatterers upon heating from 427 K to 475 K. The size distributions of the scatterers at 475 K is shown in the inset, indicating an average radius limited to ~ 14 Å at this temperature.
