Strongly exchange coupled inverse ferri FexMn3xO4, core/shell heterostructure

Inverted soft/hard, in contrast to conventional hard/soft, bi-magneti MnxFe3xO4/FexMn3xO4 with two different core sizes (7.5 and 11. (0.6 nm) have been synthesized. The structural characterization su interface with a graded composition. The magnetic characterization structure and evidences a strong exchange coupling between the cor r b ind icle the diverse constituents in a single structure.1 Importantly, the advantage of multicomponent nanostructures lies not only in multiphase systems. In the search for materials suitable for permanent magnets, biomedical applications, sensing applica-rding media, bi-magnetic CS d shell are magnetic materials, nterest, particularly since an sed to overcome the super-xt, standard and ‘‘inverse’ ’ bi-ntiferromagnetic (AFM) and tured as FM/AFM or AFM/ in the recent years.6–14 Inter-pring’ ’ magnets,15 where hard hange coupled, have been the focus of renewed effort in thin film systems for recording appli-c Dynamic Article LinksC<Nanoscal
