摘要： The present invention is an alloy that contains Fe, B, P, and Cu, and includes a non-crystalline phase and a plurality of crystalline phases formed in the non-crystalline, wherein an average Fe concentration in a whole alloy is 79 atomic % or greater, and wherein a density of Cu clusters when a region with a Cu concentration of 6.0 atomic % or greater among regions with 1.0 nm on a side in atom probe tomography is determined to be a Cu cluster is 0.20×1024/m3.
