Composites/Nano Engineering

Magnetic nanoparticles are attracting a great deal  of interest both from fundamental and applied points of view. In particular, recenty, bimagnetic core/shell nanoparticles, where both the core and the shell are magnetic, are become increasngly appealing, where passivated ferromagnetic (FM) nanoparticles coated with a corresponding antiferromagnetic (AFM) oxide shell have been intensively investigated. Here we present the study of inverted AFM core/FM shell systems.
