Nanocrystals of earth abundant transition metal oxides (NiO, CoO, Cr2O3, Fe3O4, CoFe2O4, etc.) show interesting features responsible of their magnetic response. A detailed characterization of the morphology, crystalline structure and chemistry at the surface and interfaces, helps understand and optimize their magnetic properties at the nanoscale.
