(a) Comparisons of the experimental diffuse scattering intensity distribution between the annealed i-ScZn_7.33 and i-Sc–Zn–Mg samples as measured along a twofold axis. Bragg peaks are indexed by their N and M indices following the Cahn et al. scheme. (b) Comparison between the experimental diffuse intensity measured in the i-Sc–Zn–Mg sample, and a simulated diffraction pattern of the i-ScZn_7.33 phase. The simulated diffraction pattern was obtained using the determined phason elastic constant and the phason DW factor, applied onto the experimental data of i-Sc–Zn–Mg. It reproduces well the observed one as shown in Fig. 9
