Figure 9
R–T diagram of the RSi2 and R2TSi3 compounds. The color of the markers symbolizes the range of ordering n, see Section 3.4. If the structure is disordered (AlB2, ThSi2, GdSi2), then n = 0 and the symbol is gray. If the structure is ordered, the range of ordering accords to the number of stacks along c in the unit cell. Up to three markers on one grid position are possible, representing different publications. |
