Projection of the inverse spinel structure and the HAADF-STEM image of CoFe2O4 nanoparticles. (a) Projection of the inverse spinel structure of CoFe2O4 along the <110> zone axis. Red balls represent iron atoms; green balls represent cobalt atoms; oxygen atoms have been removed for clarity. (b) Atomic resolution HAADF-STEM image of CoFe2O4 nanoparticles. Bright balls correspond to cobalt and ferrite atoms. Superimposed points are Co and Fe positions calculated from the crystal model.
