Interfacial engineering of core–shell structured FeCoNi@SnO2 magnetic composites for tunable radar-infrared compatible stealth

In this work, the core–shell structured FeCoNi@SnO2 multi-component magnetic composites were prepared by a simple method. The obtained composites not only have excellent effective absorption bandwidth (EAB) of 7.20 GHz at 1.20 mm, but also possess low infrared emissivity performance.
