摘要：
Iron oxide-based exchange-coupled nanomagnets consisting of antiferromagnetic wustite (FexO) 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. © 2009 Wiley-VCH Verlag GmbH & Co.
