Caption: This is a schematic representation of the antiferromagnetic coupling between a magnetic Fe3O4 soft core and a magnetic Mn3O4 hard shell. The image of an electronic high-resolution transmission microscope, superimposed on a map of electronic energy loss spectroscopy, reveals the high quality of the interface with a coherent increase between the two phases.
