| 摘 要： | 利用直流电化学沉积法通过调节沉积参数在多孔阳极氧化铝模板中制备出了束状形貌的Co89Cu11纳米线阵列.结构分析表明，束状结构就是沿纳米线长轴方向密集排列的堆垛层错，根据CoCu纳米线的生长机理对这种结构的形成进行了解释.在相同成分比的情况下，该结构的Co89Cu1纳米线阵列具有明显优于一般结构的矩形比（S∥=096），说明该结构的纳米线阵列的形状各向异性远好于一般结构.通过磁性测

| Abstract: | Co_89Cu_11 nanowire arrays with particular bunchy shape have been fabricated in anodic aluminum oxide templates by electrodeposition. The analysis of structure indicates that the bunchy shape of the nanowire actually is a very high concentration of stacking faults parallel to the wire. Then we give explanation to the structure according to the growth mechanism. Relatively high squareness parallel to the nanowire arrays of about 0.96 at room temperature were achieved owing to the larger shape anisotropy than... |
