摘要:The uniform and stable Fe-B amorphous magnetic nanoparticles were successfully synthesized by chemical reduction. The structures and magnetic properties of the samples were detected after annealing at different temperatures. By feature structure analysis, it can be found that there are some splitting second peaks in the pair distribution function g(r) curves, which are confirmed to be the intrinsic structure features of the amorphous alloys. Based on these, two major connection schemes of atomic packing motifs were favored in the Fe-B amorphous nanoparticles, i.e. the two-atom-shared connection and four-atom-shared connection. However there are some deviations in the cluster connections. Through the deviation degree Si, the deviations of the cluster connections from the standard two-atom-shared and four-atom-shared connections are quantified. Furthermore, it was revealed that a large deviation degree (vertical bar delta(i)vertical bar > 3%) can result in a striking decrease of the saturation flux density B-s value.
