利用磁力显微镜研究了电流驱动下非对称缺口磁线中畴壁的运动。有人发现，所需的电流驱动DW运动的临界电流密度取决于DW的传播方向。DW更容易沿不对称切口的斜率较小的方向沿着移动。(c)2005年美国物理学会。
Current-driven domain-wall (DW) motion in magnetic wires with asymmetric notches was investigated by means of magnetic force microscopy. It was found that the critical current density necessary for the current-driven DW motion depended on the propagation direction of the DW. The DW moved more easily in the direction along which the slope of the asymmetric notch was less inclined. (c) 2005 American Institute of Physics.
