TEM image of a section of a very large maghemite nanocube superlattice prepared by magnetic-field-induced self-assembly from a concentrated toluene-based dispersion of maghemite nanocubes. (Scale bar: 200 nm.) The contrast difference within the superlattice indicates that the different domains vary in layer thickness.
