X-ray study of the structure and magnetic property of the co-doped ZnO nanoparticles prepared by thermal hydrolysis

Abstract The Co-doped ZnO nanoparticles were prepared by thermal hydrolysis. A ferromagnetic moment of about 0.02 μB/Co2+ was observed at room temperature. The electronic structure of the Co-doped ZnO nanoparticles was investigated in the vicinity of the oxygen–K edge, which reveals that the magnetic origin might be due to the interactions of magnetic moment mediated by the impurity band to give a ferromagnetic state.
