Abstract: The present invention relates to a method of controlling the arrangement of building block nanocrystals in iron oxide mesocrystals by controlling the type of surface ligand, the method including mixing an iron ion precursor and a surface ligand. The present invention can provide nanoparticles having different magnetic properties by controlling the crystallographic arrangement of building block nanocrystals in mesocrystals according to surface ligands.
