Research Abstract

Fe Spin-Nano-Cluster (Fe-SNC) with high saturation magnetization and their self-organized assembly were fabricated for soft magnetic material. As a result, by applying a surfactant with weak absorption ability, Fe-SNCs with high saturation magnetization over 200 emu/g are successfully synthesized, which is due to promoting formation of bcc phase. And Fe-SNC self-organized assembly shows low coercivity 1.7 Oe, which is originated from enhanced strong magnetic dipole interaction between Fe-SNCs.
