Soft magnetic composite (SMC) materials for soft magnetic applications were developed. The most important property of SMC materials, especially those used in a high‐frequency range, is that the soft magnetic powder particles are well insulated from each other. Alloy Fe–Si–B powders were prepared by water atomization. The surface of microcrystalline powders was heat treated in dry or wet hydrogen, chemically treated and investigated by AES and XPS. The electrical breakdown voltages of the powders and SMCs were measured. Copyright © 2002 John Wiley & Sons, Ltd.
