通过在溶液中同时凝聚α-Fe纳米粒子和Au纳米粒子，制备了不同体积分数的α-Fe/Au纳米粒子组装体。在该体系中，只有偶极相互作用受到α-Fe纳米粒子间磁相互作用的影响。磁性随α-Fe纳米粒子体积分数的变化而显著变化，高体积分数的α-Fe纳米粒子组装体表现出良好的软磁性能。
Assemblies of α-Fe/Au nanoparticles (NPs) with various volume fractions of α-Fe NPs were prepared by simultaneous agglomeration of α-Fe NPs and Au NPs in solution. Only the dipole interaction was affected by the magnetic interaction between α-Fe NPs in this system. The magnetic properties were significantly changed according to the volume fraction of the α-Fe NPs, with a high α-Fe NP volume fraction assembly exhibiting good soft magnetic properties.
