Ni 1-x Zn x Fe 2 O 4 / MWCNTs nanocomposites(x=0.4,0.5,0.6) with controllable composition have been successfully fabricated via microwave-assisted polyol route using triethylene glycol solution(TREG) as solvent.The structure and morphology of the final products were characterized by XRD,SEM,TEM and EDX.The magnetic properties were measured by VSM.The influence of microwave power and microwave time on loading has also been investigated.The results show that the spinel Ni1-xZnxFe2O4nanoparticles with a facece...
