| 摘 要： | "在阳极氧化铝模板的孔洞中利用模板浸润的方法成功制备出了铁镍合金纳米管阵列．通过改变所用模板的参数和沉积纳米管的的制备条件,所制备的纳米管的长度、内径和外径的尺寸都可以得到有效控制．利用扫描电子显微镜和透射电子显微镜对所制备的纳米管及其阵列的形貌进行了表征．对铁镍合金纳米管阵列的宏观磁性测量表明样品具有磁各向异性,沿纳米管长轴方向样品更容易被磁化．对纳米管的磁化反转机制和磁矩在纳米管中的静态分布进行了讨论．铁镍合金纳米管的这些性质都是由纳米管的独特结构造成的．"

| Abstract: | "FeNi nanotubes were successfully prepared in pores of anodic aluminium oxide templates by the wetting template method. By varying the deposition conditions and the parameters of the templates, the lengths and the outer as well as the inner diameters of the tubes can be tailored. The FeNi nanotubes and their arrays were characterized by transmission and scanning electron microscopy. Macroscopic magnetic measurements show the FeNi nanotube arrays to have obvious anisotropy, and the easy axis is parallel to the nanotube axis. The magnetic moment distributions in the tube walls and the magnetization reversal mechanism are discussed. Magnetic moments of the FeNi nanotube preferentially lie in the nanotube wall, but the distribution is spatially isotropic. These magnetic behaviours are due to the unique shape of the nanotube." |
