(a) Images of SAF nanoparticles in a 20 µm deep chamber slide in zero field and at 1010/ mL initial concentration. (b) Chain structures formed 50 seconds after H was increased to 1 kOe, 1010/ mL. (c) Small chains which form under the same conditions, except the concentration is 109/ mL. (d) Numerous chains formed in 15 sec when the concentration is 1011/ mL.
