Abstract
Official abstract text for this publication.
A nanogranular magnetic film includes first phases comprised of nano-domains dispersed in a second phase. The first phases include Fe and Co. The second phase includes at least one selected from the group consisting of O, N, and F. A CV of Fe/(Fe+Co) of grids is 0.150 or more and 0.500 or less, provided that a measurement range is determined in the nanogranular magnetic film, the measurement range is divided with the grids including at least 80,000 grids each measuring 1 nm×1 nm×1 nm, and Fe/(Fe+Co) of each of the grids is measured in atomic ratio.
First claim
Opening claim text (preview).
What is claimed is: 1 . 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 at least one selected from the group consisting of O, N, and F; and a CV of Fe/(Fe+Co) of grids is 0.150 or more and 0.500 or less, provided that a measurement range is determined in the nanogranular magnetic film, the measurement range is divided with the grids comprising at least 80,000 grids each measuring 1 nm×1 nm×1 nm, and Fe/(Fe+Co) of each of the grids is measured in atomic ratio. 2 . The nanogranular magnetic film according to claim 1 , wherein a volume ratio of a volume of the first phases to a total volume of the first phases and the second phase is 40% or more and 65% or less. 3 . The nanogranular magnetic film according to claim 1 , wherein Fe/(Fe+Co) of the grids averages 0.15 or more and 0.85 or less. 4 . An electronic component comprising the nanogranular magnetic film according to claim 1 .
