Figure 7
(a) Mg and (b) Cu partial structures of the cubic Laves phase cF24-MgCu₂. Average structures of (c)–(d) AT-19 (a = 6.384 Å), (e)–(f) ACT-45 (a = 6.495 Å) and ACT-71 (a = 6.499 Å). The Ta partial structures are depicted in (c), (e) and (g), those of Al in (d), (f) and (h). In all cases, projections along [001] of half a unit cell are shown.
