(a) Rare-earth sites ( Å around the origin) in the f-Zn–Mg–R icosahedral quasicrystals generated using the parameters determined by the synchrotron-radiation powder X-ray experiment (Ishimasa et al., 2003). (b) Magnified illustration of the edge-sharing dodecahedral network of the rare-earth sites; only atoms participating in the network are shown. |
