摘要

One dimensional (Mn, Li) co-doped ZnO nanorods have been prepared using electrodeposition method at constant current mode. Room temperature ferromagnetism and ferroelectricity were found coexisted in the co-doped ZnO nanorods and the underlying mechanism were discussed. The origin of the ferroelectric behavior could be explained on the basis of the ionic radii difference between the Zn~2+ (0.74 A) and the dopants ions while the ferromagnetism can be explained by a bound magnetic polaron mode and influenced by oxygen vacancies. Electron microscopy results show that the nanorod is straight with a diameter of about 80-100 nm and the density of nanorods arrays is increased when the MnCl_2 concentrations increase from 0.01 to 0.02 mol/L X-ray diffraction results confirm that the ZnO nanorods arrays are polycrystalline structure and with a (0 0 2) preferential orientation.
