Figure 4
(a) Interdiffusion coefficient $[\tilde{D}]$ for several combinations of bilayer period and heating rate. Labels A, B and C identify the peaks in $[\tilde{D}]$ for the multilayer with $[\Lambda]$ = 25 nm discussed in the main text and referenced in Fig. 5

. The inset shows the data for $[\Lambda]$ = 20 nm in more detail. (b) Arrhenius plot for determination of activation energy E_a for the $[\Lambda]$ = 25 nm sample from part (a). The fit is to the five data points from the lowest temperature range (485 K to 530 K).
