磁性纳米线中电流驱动的磁畴壁运动在物理研究和工程应用中引起了极大的兴趣。磁力显微镜（MFM）被广泛用于纳米线中畴位置的间接验证，其中局部畴和MFM探针之间的相对磁力用于检测。然而，偶尔会出现这样的问题，即MFM探针的磁矩影响和/或旋转低磁矩纳米线中的磁性状态。为了解决这一问题，最近提出了“纳米级分辨率的大范围磁畴探测器”（Nano-MDS）方法，该方法可以通过隧道磁阻场传感器的扫描直接检测样品中的磁通量分布。在这项研究中，磁畴结构的纳米线进行了研究，MFM和纳米MDS，从纳米线的漏磁通密度定量测量纳米线。样品纳米线由[Co（0.3）/Pd（...
Current-driven magnetic domain wall motions in magnetic nanowires have attracted great interests for physical studies and engineering applications. The magnetic force microscope (MFM) is widely used for indirect verification of domain locations in nanowires, where relative magnetic force between the local domains and the MFM probe is used for detection. However, there is an occasional problem that the magnetic moments of MFM probe influenced and/or rotated the magnetic states in the low-moment nanowires. To solve this issue, the “magnetic domain scope for wide area with nano-order resolution (nano-MDS)” method has been proposed recently that could detect the magnetic flux distribution from the specimen directly by scanning of tunneling magnetoresistive field sensor. In this study, magnetic domain structure in nanowires was investigated by both MFM and nano-MDS, and the leakage magnetic flux density from the nanowires was measured quantitatively by nano-MDS. Specimen nanowires consisted from [Co (0.3)/Pd (...
