Figure 6
ATS scattering of the charge resonance at the (4, 2, 0) diffraction order in Cd2Os2O7. Both the sample mosaic at E = 12.387 keV and energy scans across the Os L2 edge are compared side-by-side for four different pressures across the pressure-induced magnetic phase boundary at Pc = 35.8 GPa (Wang et al., 2018BB61). The high-pressure phase beyond Pc can be ascribed to the [F\bar{4}3m] space group, where the lattice (4, 2, 0) order becomes no longer forbidden. The ATS resonance signal is eventually overwhelmed by non-resonant lattice diffraction at P = 41 GPa.
