Magnetic Materials: Novel Nanostructured Rare‐Earth‐Free Magnetic Materials with High Energy Products (Adv. Mater. 42/2013)

The development of new magnetic materials is of paramount importance to surmount significant worldwide challenges in energy and environmental security. On page 6090, David J. Sellmyer, Balamurugan Balasubramanian, and co-workers report a novel hybrid nanomagnetic material having the highest energy product for permanentmagnet materials free of critical rare-earth elements or expensive Pt. This is achieved in a single-step process by assembling the easy-axis aligned high-anisotropy nanoparticles with a high-magnetization soft Fe-Co phase.
