Polar maps of CB in radians of a 517 µm crystal of the P43212 enantiomorph. (a) Experimental map along [001] (left) and calculated map along [001] (right) with a maximum angle of incidence equal to 30°. (b) Calculated map of a crystal cut normal to [010] with a maximum angle of incidence equal to 80°. (c) Calculated map of a crystal cut at 63.9° from [001] with a maximum angle of incidence equal to 80°. The white dashed lines represent polar positions associated with eigendirections. (d) Normalized representation surfaces of the magnetoelectric tensor, (left), and of the optical rotation tensor, (° mm−1; right), plotted with the software WinTensor (https://cad4.cpac.washington.edu/WinTensorhome/WinTensor.htm). The double cone of eigendirections is overlaid in black, and the dashed lines indicate the viewing directions depicted in the polar maps in panels (a), (b) and (c). |
