Figure 9
Temperature dependence of degree of atomic displacement parameter elongation (ellipsoidality) of oxygen, boron, yttrium and iron atoms in the (Y0.95Bi0.05)Fe3(BO3)4 structure. The labels of atoms in the low-temperature space group P3121 are shown and their equivalent in the high-temperature (HT) space group R32 are given in parentheses. Dashed line indicates the Tstr = 370 K. |
