Figure 3
(a) A photograph and the crystal orientation of the Co6.75Zn6.75Mn6.5 single crystal studied by SANS. (b) Schematic diagrams of the two experimental geometries studied by SANS. In each geometry the neutron beam direction (ki) is normal to the largest face of the plate-like sample. The geometries differ according to the direction of the magnetic field H, with H ∥ ki on the left and H ⊥ ki on the right. (c)–(g) SANS patterns measured during ZFC at 100, 90, 80, 50 and 1.5 K, respectively. The intensity scale of the colour plot varies in each panel. The crystal orientation indicated for the SANS patterns in panels (c)–(g) is the same as for panel (a). |
