Nanocrystalline Co -doped ZnO ( Zn 1-x Co x O , x = 0.00, 0.05) powders have been successfully prepared by a microwave-assisted combustion method using Zn ( NO 3)2·6 H 2 O and Co ( NO 3)2·6 H 2 O as starting materials and urea as fuel. The as-prepared products were characterized by X-ray diffractometer (XRD), scanning electron microscope (SEM) and vibrating sample magnetometer (VSM). It was found that the combustion process took only a few minutes to obtain Zn 1-x Co x O powders. The field dependence of magnetization measurement at room temperature for the as-prepared Zn 0.95 Co 0.05 O powders exhibited the obvious ferromagnetic behavior.
