External magnetic fields direct the destabilization and anisotropic aggregation of CoPt 3 nanocrystal dispersions, producing one‐dimensional nanocrystal microwires. These microwires comprise disordered assemblies of discrete nanocrystals (see Figure). The observed activated‐charge‐transport properties of the microwires are determined by charging of individual nanocrystals.
