摘要
采用电沉积法在平均孔径为240 nm和200 nm的al2o3模板(NCA100和NCA20)中生长镍纳米线。利用扫描电子显微镜(SEM)研究了纳米线的生长过程。x射线衍射分析表明，纳米线具有多晶性质，平均晶粒尺寸在24 ~ 35 nm之间。平均晶粒尺寸和晶体取向取决于电解质的pH值和温度。采用振动样品磁强计(VSM)研究了镍填充纳米孔阵列的体磁性能。在NCA20中沉积12.5μm长的纳米线，其矫顽力高达19.42 kA m-1。利用原子力显微镜(AFM)和磁力显微镜(MFM)研究了纳米线在模板内的表面形貌和磁畴结构。
AFM and MFM Study of Electrodeposited Ni Nanowires Grown Inside Pores of NCA Templates
Nickel nanowires were grown by electrodeposition within Al2O3templates (NCA100 and NCA20) having average pore diameters of 240 and 200 nm. The growth of nanowires was investigated by Scanning Electron Microscopy (SEM). X-ray diffraction analysis shows polycrystalline nature of the nanowires having average crystallite size varying from 24 to 35 nm. Average crystallite size and the crystal orientation were dependent on the pH and temperature of the electrolyte. Bulk magnetic properties of nickel filled nanoporous arrays were investigated using the Vibrating sample magnetometer (VSM). Coercivity as high as 19.42 kA m-1was obtained from 12.5μm length nanowires deposited inside NCA20. Atomic Force Microscopy (AFM) and Magnetic Force Microscopy (MFM) were employed to investigate the topography and magnetic domain structures on top of these nanowires when they reside inside the templates.
