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., 2018). The high-pressure phase beyond Pc can be ascribed to the 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. |
