Abstract

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.
