Figure 6
Variation of (a) lattice parameters a, b, c, and cell volume, and (b) the angles , , , , of β- and β′-CaTeO3 with temperature. Measurements of β- and β′-CaTeO3 are indicated by triangles and squares. The text next to the symbol indicates the space group, a subscript `d' meaning a disordered structure. Error bars have been omitted since they are smaller than the symbol sizes. |
