Stabilizing interface of SmCo_(5)/Co nanocomposites by graphene shells

摘要

In this work,we proposed a novel chemical strategy to synthesize exchange-coupled SmCo_(5)/Co nanocomposites by using graphene shells to stabilize the interface.In our synthesis,the SmCo-OH/GO(graphene oxide)precursor prepared by co-precipitation method could be first reduced by calcium to yield 15-nm SmCo_(5)/GN(graphene)single-crystal nanoparticles,and then 8-nm Co particles were deposited on the surface of SmCo_(5)/GN to yield SmCo_(5)/GN/Co nanocomposites.
