Iron oxide‐based exchange‐coupled nanomagnets consisting of antiferromagnetic wüstite (Fe x O) cores covered by ferrimagnetic metal ferrite shells (see figure) are chemically synthesized in a simple one‐pot procedure. The synthesis allows independent size, shape, and compositional control. The strong exchange coupling at the core/shell interface results in unique magnetic properties.
