Figure 13
The (a) τ angle is the angle that the P1—Ox bond direction makes with the a axis when projected on the ab plane is plotted for (b) SrZP and (c) CaZP. Definition of the τ angle is shown in (a) the [R{\bar 3}] space group in black text and the [R{\bar 3}c] space group in red text. Thermal evolution of τ is described with the [R{\bar 3}] nomenclature. Datasets are shown for both heating and cooling.
