| 中文摘要 | The authors report the current-voltage characteristics of CaMnO3-delta/La0.69Ca0.31MnO3 heterojunctions prepared under different oxygen pressures. The most interesting observation is that the heterojunctions made under low oxygen pressure shows an ultrasharp current jump in the current-voltage curves and the nonlinear coefficient can reach similar to 2x10(4). They also show remarkable magnetoresistance. The results can be understood in terms of the oxygen vacancy related defects at the junction interface. This work shows that all-manganite-based heterojunctions can show giant nonlinear coefficient, which may have potential applications. (C) 2007 American Institute of Physics. |
