Exfoliated BN shell-based high-frequency magnetic core-shell materials


The miniaturization of electric machines demands high frequency magnetic materials with large magnetic-flux density and low energy loss to achieve a decreased dimension of high rotational speed motors. Herein, we report a solution-processed high frequency magnetic composite - nanometal FeCo core and boron nitride (BN) shell - which simultaneously exhibits high electrical resistivity and magnetic permeability. The frequency dependent complex initial permeability and mechanical robustness of nanocomposites is intensely dependent upon the content of BN insulating phase. The results shown here imply that the insulating magnetic nanocomposites have the potential to be used in the next generation high-frequency electric machines with large electrical resistivity and permeability.
