Zn{sub 0.96}Mn{sub 0.04}O/ZnO coaxial nanocable and Zn{sub 0.96}Mn{sub 0.04}O film were prepared by two-step method and magnetron sputtering, respectively. The x-ray diffraction analysis reveals that Mn is incorporated well into the wurtzite ZnO without formation of Mn or Mn oxide. The high resolution transmission electron microscopy image and the selected-area electron diffraction pattern demonstrate that both ZnO and Zn{sub 0.96}Mn{sub 0.04}O layers are single crystalline and an epitaxial growth is achieved between Zn{sub 0.96}Mn{sub 0.04}O and ZnO in the coaxial nanocable. The magnetic property measurements show that both Zn{sub 0.96}Mn{sub 0.04}O/ZnO nanocable and Zn{sub 0.96}Mn{sub 0.04}O film are ferromagnetic at room temperature. Moreover, the saturated magnetization and the coercive field of Zn{sub 0.96}Mn{sub 0.04}O/ZnO coaxial nanocable are larger than those of Zn{sub 0.96}Mn{sub 0.04}O film.
