Room Temperature Ferromagnetism in Nanostructure Cu-Doped ZnO
Cu掺杂ZnO纳米结构的室温铁磁性研究

A series of Zn1-xCuxO(x=0.01,0.02,0.030.04)nanoparticles were synthesized from Zn nitrate and Cu nitrate reduced by citrate.X-ray diffraction(XRD)shows that Zn1-xCuxO samples are single phase with ZnO-like wurtzite struc ture.Magnetic measurements indicate that Zn1-xCuxO(x=0.01,0.02,0.030.04)are ferromagnetic at room temperature.XRD,transmission electron microscope(TEM)analysis,and X-ray photoelectron spectroscopy(XPS)reveal that no ferromagne tic-related secondary phase was detected.The ferromagnetism in Z...
