Abstract
- Abstract: Co-doped ZnO single-crystalline nanorods with 80–100nm in diameter and 1.5–2μm in length have been prepared in a simple solution route. X-ray diffraction data and selected area electron diffraction pattern of the diluted magnetic semiconductor nanorods confirm the single crystallinity of Zn1− x Co x O solid solution without impurities of metallic Co or other phases. Magnetic results show that the Zn0.95Co0.05O nanorods exhibit a ferromagnetic characteristic with Curie temperature higher than 380K. The high-temperature ferromagnetic properties allow this Zn1− x Co x O nanorods potential applications in future spintronic devices. [Copyright &y& Elsevier]
