Role of nanoparticle shape on the critical size for quasi-uniform ordering: from spheres to cubes through superballs

Iago López-Vázquez, David Serantes, Òscar Iglesias

The equilibrium states of single-domain magnetite nanoparticles (NPs) result from a subtle interplay between size, geometry, and magnetocrystalline anisotropy. In this work, we pre…
