▎ 摘　　要

Co1-xNixFe2O4/graphene nanocomposites were synthesized through a one-step solvothermal method. The as-synthesized products were characterized by X-ray powder diffraction, field emission scanning microscopy, transmission electron microscope, and high-resolution transmission electron microscope. The results show that the Co1-xNixFe2O4 nanoparticles are uniformly dispersed on graphene sheets. The dependence of structure, magnetic and electrical properties of Co1-xNixFe2O4/graphene nanocomposites on the Ni2+ concentration and the graphene content were also studied. The saturation magnetization and electrical conductivity of the as-prepared products reached 51.82 emu/g and 1.00 x 10(2) S/m, respectively. (C) 2012 Published by Elsevier B.V.
