STRUCTURES AND METHODS UTILIZING STRUCTURED MAGNETIC MATERIAL

摘要

A composition comprises a plurality of iron-containing particles and an insulating layer on the iron-containing particles. The iron-containing particles define an aggregate of permeable micro-domains separated by insulation boundaries. A method comprises heating an iron-aluminum alloy particle, thermally spraying the iron-aluminum particle', causing the iron-aluminum particle to oxidize, and depositing the oxidized iron-aluminum particle on a substrate.
