Face-Centered-Cubic "Supracrystals" of Cobalt Nanocrystals

Magnetic “supra” crystals have been built by slow evaporation of a solution of 7.2 nm cobalt nanoparticles in hexane. Scanning electron microscopy shows isolated pavements which height is of the order of 5 μm (see Figure). Investigation made by small‐angle X‐ray diffraction clearly indicates a face‐...

Summary:Magnetic “supra” crystals have been built by slow evaporation of a solution of 7.2 nm cobalt nanoparticles in hexane. Scanning electron microscopy shows isolated pavements which height is of the order of 5 μm (see Figure). Investigation made by small‐angle X‐ray diffraction clearly indicates a face‐centered cubic structure.
