Figure 7
(a) 3D visualization of the low-angle region of diffraction patterns collected on D1B (l = 2.52 Å). The abrupt background change and the simultaneous emergence of the kc2 = (0, 0, 0) magnetic peaks indicates a first-order magnetic transition. (b) Detailed evolution of diffraction patterns for Ho2BaCuO5 around the transition at ≈8 K. The peak indexing [blue for kc1 = (0, ½, 0) and red for kc2 = (0, 0, 0)] is referenced to the paramagnetic unit cell.
