      abstract     = {Interest in creating magnetic metamaterials has led to
                      methods for growing superstructures of magnetic
                      nanoparticles. Mesoscopic crystals of maghemite (γ-Fe2O3)
                      nanoparticles can be arranged into highly ordered
                      body-centered tetragonal lattices of up to a few
                      micrometers. Although measurements on disordered ensembles
                      have been carried out, determining the magnetic properties
                      of individual mesoscopic crystals is challenging due to
                      their small total magnetic moment. Here, we overcome these
                      challenges by utilizing sensitive dynamic cantilever
                      magnetometry to study individual micrometer-sized γ-Fe2O3
                      mesocrystals. These measurements reveal an unambiguous cubic
                      anisotropy, resulting from the crystalline anisotropy of the
                      constituent maghemite nanoparticles and their alignment
                      within the mesoscopic lattice. The signatures of anisotropy
                      and its origins come to light because we combine the
                      self-assembly of highly ordered mesocrystals with the
                      ability to resolve their individual magnetism. This
                      combination is promising for future studies of the magnetic
                      anisotropy of other nanoparticles, which are too small to
                      investigate individually.},
