| 中文摘要 | Multiphase Fe-oxide thin films are fabricated on glass substrates by a facing-target sputtering technique. X-ray diffraction and X-ray photoelectron spectroscopy reveal that Fe, FeA, rFe(2)O(3) and FeO coexist in the films. High resolution transmission electron microscopy shows the well-defined columnar grain structure with the unoxidized Fe as the core and iron-oxide as the shell. The low-field positive and high-field negative magnetoresistances coexist in such a system at room temperature, which can be explained by considering a shell/core model. Nonlinear current-voltage curve and photovoltaic effect further confirm the tunneling-type conduction. |
