Nanolithography techniques in a scanning electron microscope/focused ion beam are very attractive tools for a number of synthetic processes, including the fabrication of ferromagnetic nano-objects, with potential applications in magnetic storage or magnetic sensing. One of the most versatile techniques is the focused electron beam induced deposition, an efficient method for the production of magnetic structures highly resolved at the nanometric scale. In this work, this method has been applied to the controlled growth of magnetic nanostructures using Co2(CO)8. The chemical and structural properties of these deposits have been studied by electron energy loss spectroscopy and high-resolution transmission electron microscopy at the nanometric scale. The obtained results allow us to correlate the chemical and structural properties with the functionality of these magnetic nanostructures.
扫描电子显微镜/聚焦离子束中的纳米光刻技术是多种合成工艺中极具吸引力的工具，包括铁磁纳米物体的制造，在磁存储或磁传感方面具有潜在应用。最通用的技术之一是聚焦电子束诱导沉积，这是一种在纳米尺度上高效生产高分辨率磁性结构的方法。在这项工作中，该方法已应用于使用Co2(CO)8控制磁性纳米结构的生长。通过电子能量损失谱和纳米尺度的高分辨率透射电子显微镜研究了这些沉积物的化学和结构性质。所得结果使我们能够将化学和结构性质与这些磁性纳米结构的功能联系起来。
