Figure 3
Longitudinal (θ–2θ) diffraction line shapes of the (4, 0, 0) lattice order of Cd2Os2O7. The measurements were carried out using 12.387 keV X-rays in a Laue (transmission) geometry through samples of ∼15 µm thickness. The system remains in the cubic structure up to 41 GPa, while the gradually broadened line shapes with increasing pressure demonstrate the pressure-gradient condition experienced by the single-crystal sample. |
