Rare-earth intermediate phases with zinc.
TLDR
In this article, the existence and the structure of the rare earth-zinc intermediate phases in the range 75-88 at.% Zn has been investigated: the compositions MZn3, M3Zn11,MZn4, M13Zn58, MZnsn5, M 3Zn17 and M 3 Zn22 were examined.Abstract:
The existence and the structure of the rare earth-zinc intermediate phases in the range 75–88 at.% Zn has been investigated: the compositions MZn3, M3Zn11, MZn4, M13Zn58, MZn5, M3Zn17 and M3Zn22 were examined. A part of the Er-Zn system has been studied by differential thermal analysis. The different types of structure occurring in these intermetallic phases were correlated through the coordination number of the component atoms. The trend of the rare-earth coordination number appears to be related to the existence of ranges of the different phases. In the series of isomorphous compounds, the known, linear dependence of the lattice dimensions upon the rare-earth trivalent ionic radii is confirmed.read more

Coloring, Distortions, and Puckering in Selected Intermetallic Structures from the Perspective of Group‐Subgroup Relations
TL;DR: A review of the use of Barnighausen trees for classification of intermetallic structures into structural families can be found in this paper, where the main focus lies on more complex structures that derive from aristotypes with comparatively high space group symmetry: AlB2, Fe2P, U3Si2, BaAl4, La3Al11, NaZn13, CaCu5, and Re3B.
