Abstract:

High temperature inductor applications require improved magnet performance, including simultaneous high magnetization and low core losses at ever higher operation frequencies. Conventional polycrystalline soft magnet alloys are mature technologies with little room for meaningful improvement. Recently, nanocrystalline soft magnetic materials possessing reduced hysteretic losses and offering higher operation frequencies than conventional alloys have been introduced. These nanocrystalline soft magnets with compositions Fe-Co-Zr-B-Cu have been offered as alternatives to the conventional alloys. This paper describes the processing, structure, and magnetic properties of these materials.
