More Information
Summary:To provide soft magnetic metal powder which comprises fine particles which can be used to produce a high-density powder compact, and from which not only a powder magnetic core having excellent magnetic characteristics can be produced because of a small content of boron used for reduction of saturation magnetization, but also a thin film having excellent surface smoothness can be formed because the powder is an aggregation of fine particles having a narrow particle size distribution. Soft magnetic metal powder having an average particle diameter of 0.05 [mu]m to 1.5 [mu]m, a change coefficient of 0.25 or less as expressed by the (Expression) given below, and a boron content of less than 5.0 Wt% (provided that 0 is excluded). (Expression): Standard deviation of particle diameter/average particle diameter.
