Room Temperature Ferromagnetism in Nanostructure Cu-Doped ZnO

Abstract
A series of Zn1-xCuxO(x=0.01,0.02,0.03,0.04) 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 structure.Magnetic measurements indicate that Zn1-xCuxO(x=0.01,0.02,0.03,0.04) are ferromagnetic at room temperature.XRD,transmission electron microscope (TEM) analysis,and X-ray photoelectron spectroscopy (XPS) reveal that no ferromagnetic-related secondary phase was detected.The ferromagnetism in Zn1-xCuxO (x≤0.04) is intrinsic.-
