Nanogranular magnetic film and electronic component

A nanogranular magnetic film comprising:

• first phases comprised of nano-domains dispersed in a second phase,
• wherein
• the first phases comprise Fe and Co;
• the second phase comprises a second phase compound comprising at least one selected from the group consisting of O, N, and F;
• and
• a CV of Fe/(Fe+Co) of MX-rich grids is larger than a CV of Fe/(Fe+Co) of MX-poor grids,
• provided that
• a measurement range is determined in the nanogranular magnetic film,
• the measurement range is divided with grids comprising at least 80,000 grids each measuring 1 nm×1 nm×1 nm,
• Fe/(Fe+Co) and a concentration of the second phase compound of each of the grids are measured in atomic ratio,
• the grids are classified into the MX-rich grids and the MX-poor grids,
• the concentration of the second phase compound in the MX-rich grids is not lower than an average concentration of the second phase compound, and
• the concentration of the second phase compound in the MX-poor grids is lower than the average concentration of the second phase compound.
