Figure 5
Magnetic field-dependent two-dimensional diffraction patterns of (a)–(c) nanocrystalline (D = 33 nm) and (d)–(f) coarse-grained (D ≳ 100 nm) Ho at 50 K after ZFC. H is horizontal in the plane of the detector and increases up to 5 T (virgin-curve data). The central square in each figure masks the region of the beam stop. The white dashed circles labelled `A' and `B' refer to features discussed in the main text. |
