Figure 2
Expansion indicatrices of the three compounds. Each panel shows three sections of the indicatrix, viewed along each of the Cartesian coordinates, with the corresponding unit cell vectors and expansion eigenvectors (EV) labelled. Blue sections show thermal expansion and red the expansion due to radiation. The pink lines indicate negative expansion induced by radiation. Where the thermal and radiation expansion share the same eigenvectors, these are shown in black, otherwise they are shown in blue and red, respectively. To make the thermal expansion (in K−1) and radiation expansion (in Gy−1) a comparable size in the diagram, the radiation expansion has been multiplied by the figure given in red in the top right of each panel.
