| 摘 要： | 采用交流电化学沉积法在氧化铝模板孔洞中制备了有序钴纳米线阵列。利用X射线衍射、扫描电子显微镜、透射电子显微镜、振动样品磁强计等对样品的结构、形貌和磁性进行了表征和研究。扫描电镜表明氧化铝模板孔洞直径为20 nm,结构研究证明钴纳米线为六角密堆积(HCP)结构且具有很强的(002)织构,磁性测试发现该钴纳米线阵列具有很强的单轴各向异性,室温矫顽力达2 590 Oe,有望用于高温永磁磁记录。

| Abstract: | Cobalt nanowire arrays have been fabricated in the pores of anodic alumimum oxide(AAO) templates by electrodeposition.Microstructure and magnetic properties performed by X-ray diffraction,scanning electron microscopy,transmission microscope and vibrating sample magnetometer.It is found that the diameter of pores of AAO templates is 20 nm,and Co nanowire arrays are hexagonal close-packed structure with(002) texture.Magnetic measurement show the Co nanowire arrays have strong uniaxial anisotropy,its coercivity up to 2590 Oe at 300 K,which can be considered as magnetic recording. |
