a Representative TEM images of Fe3O4 nanocrystals synthesized via thermal decomposition process; b Fe3O4 arrays formed after the high-pressure compression. c HR-TEM image of the Fe3O4 nanowires. d HR-STEM image of the Fe3O4 particles in the chains. e SAXS pattern of Fe3O4 nanocrystal arrays at varied pressures, here r is used to display the releasing pressure. The superlattice d111-spacing calculated from first Bragg peak is shown in Fig. S2.
