  • Publication number: 20240071663
    Abstract: A soft magnetic alloy powder comprises first particles to fifth particles, each having a particle size within a specific range. Among the first particles to the fifth particles, nth particles have an average particle size xn (?m), an average circularity yn, and a variance zn of circularity, where nth is any ordinal number from first to fifth. Points (xn, yn) (n=1 to 5) plotted in an xy plane define an approximate straight line having a slope “my” of ?0.0030 or more. Points (xn, zn) (n=1 to 5) plotted in an xz plane define an approximate straight line having a slope “mz” of 0.00050 or less.
