利用电沉积法在多孔阳极氧化铝模板中组装了镍纳米管阵列,分别利用SEM、TEM、XRD和VSM对镍纳米管的形貌、结构和磁性能进行表征.结果表明,所制备的镍纳米管阵列,属面心立方(fcc)结构,磁滞回线表明制备的镍纳米管阵列具有磁单轴各向异性和单磁畴特性.

Ni nanotube arrays had been fabricated in PAA template by electrodeposition.The morphology, structure and magnetic properties of Ni nanotube arrays were characterized by SEM, TEM, XRD and VSM, respectively.The results show that the fabricated Ni nanotube arrays were (fcc) in structure and the shape and size of Ni nanotube arrays were uniform and on a large-scale.The hysteresis loops show that Ni nanotube arrays had been marked magnetic single-axis anisotropy and the property of single domain.
