(a) Image of the low-temperature setup at the general purpose experiment of the ECB consisting of a modified cold-finger cryostat from Oxford Instruments. (b) Diffraction image of the hk plane of La1.67Sr0.33NiO4 at T = 150 K and P = 6.5 GPa, with parts of l integrated by sample rotation. The four intense Bragg reflections are labelled with Miller indices (h, k, l). The charge stripe order peaks (h, 0, 3), with h = 4.67, 5.33, 6.67 and 7.33, are marked by circles. Also visible are the corresponding charge order peaks with k = 2 on the right-hand side of the image. |
