Summary
| Description |
English: Ho-Mg-Zn dodecahedral quasicrystal, grown by using the self-flux method (excess Mg), and slowly cooling from 700 C to 480 C. The R-Mg-Zn family is the first rare-earth containing quasicrystal structure, which allows the study of localized magnetic moments in a quasiperiodic environment.
Or: Photograph of a single-grain icosahedral Ho-Mg-Zn quasicrystal grown from the ternary melt. Shown over a mm scale, the edges are 2.2 mm long. Note the clearly defined pentagonal facets, and the dodecahedral morphology. [in: Phys. Rev. B 59, 308–321 (1999)] |
