    Controlling properties of metal–polymer soft magnetic composites through microstructural deformation for power inductor applications

    We studied the effect of microstructural deformation on soft magnetic metal powders in a power inductor operating above 1 MHz. In this study, an inductor core was fabricated using Fe-6.5Si powders that exhibit...
