(a) SANS data with Q < 0.06 Å−1, (b) the 2D correlation function with r < 50 Å, and (c) the 1D correlation functions parallel (orange) and perpendicular (blue) to the applied field direction for the concentrated dispersion of spherical nanoparticles. The applied magnetic fields of 0.05, 0.4, 1.1 and 1.54 T (left to right) are indicated as horizontal arrows. |
