摘要：

We report the room temperature ferromagnetism of Cu doped ZnO nanowire arrays embedded in anodic aluminum oxide template. The nanowires about 100 nm in diameter were fabricated by electrodepositing Zn2+ and Cu2+ into the template and postoxidation annealing in air atmosphere. Magnetization measurements indicated that the Zn1-xCuxO (x=0.05 and 0.07) nanowires exhibit room temperature ferromagnetism and the Zn0.93Cu0.07O nanowires annealed in vacuum reveals an enhancement of the ferromagnetism. X-ray diffraction pattern, x-ray photoelectron spectroscopy, and Raman spectra measurements showed that all the samples possess a typical wurtzite structure and no other impurity phases were observed.
