Nanocrystal metamaterials : The self‐ assembly of ordered solids comprised of nanocrystals with different properties is of great interest. Ordered two‐ and three‐dimensional nanocrystal superlattices with a rock salt structure (see graphic) were formed by drying a dispersion containing large magnetic (iron) and small noble metal (gold) nanocrystals with carefully controlled size ratios.
