| 摘 要： | 利用二次阳极氧化法制备了多孔阳极氧化铝模板. 用直流电化学沉积方法成功地在模板孔道内制备了钴纳米线. 采用扫描电子显微镜(SEM)、X射线衍射仪(XRD)和振动样品磁强计(VSM)对样品的形貌、晶体结构和磁性进行了研究. 结果表明， 模板的孔径均匀, 孔道平直. 钴纳米线为多晶的六方密堆积结构. 钴纳米线具有明显的磁各向异性, 这主要起源于纳米线的形状各向异性.

| Abstract: | Porous anodic aluminium oxide(AAO) template was fabricated by two-step anodization. Cobalt nanowires were formed in the pores of AAO template by using dc electrochemical deposition. The structure and magnetic properties of the sample were studied by scanning electron microscopy(SEM), X-ray diffraction(XRD) and vibrating sample magnetometer(VSM). The results show that the pores of the template were straight and had nearly the same diameter. Cobalt nanowires are hcp polycrystal. The cobalt nanowires show a clear magnetic anisotropy. This is mainly due to shape anisotropy. |
