Abstract
A nanogranular magnetic film has a structure including a second phase and first phases dispersed in the second phase. The first phases include nanoscale metal phases containing Fe and Co. The second phase contains oxygen and nitrogen. The metal phases include one or more crystallites. The one or more crystallites have crystallite sizes with a mode of 1.5 nm or more and 6.0 nm or less based on volume.
