利用空间分辨磁光克尔效应测量了聚焦式电子束诱导沉积钴纳米线的磁壁成核场和传播场。系统地研究了从600到150 nm的导线宽度，发现导线的两个场的值存在显著差异，表明高质量的磁区壁导管行为。相对于当今使用的多步骤光刻工艺，这一技术的极端简单性和灵活性开辟了一条不同的路线，可以很好地控制磁化壁的运动来制造磁性纳米结构。
The domain wall nucleation and propagation fields in cobalt nanowires grown by focused electron beam induced deposition are measured using spatially resolved magneto-optical Kerr effect. The study was systematically done for wire widths from 600 to 150 nm, finding significant differences in the value of both fields for the wires, indicating high quality domain wall conduit behavior. The extreme simplicity and flexibility of this technique with respect to the multistep lithographic processes used nowadays opens a different route to create magnetic nanostructures with a good control of the domain wall motion.
