利用巨磁阻效应研究了由具有不对称切口的磁性/非磁性/磁性三层结构组成的亚微米磁线中磁畴壁（DW）的传播。 DW 的传播方向由脉冲局部磁场控制，该磁场使 DW 在线两端之一成核。结果发现，DW 从凹口的脱钉场取决于 DW 的传播方向。 (C) 2005 年美国物理研究所。
The propagation of a magnetic domain wall (DW) in a submicron magnetic wire consisting of a magnetic/nonmagnetic/magnetic trilayered structure with asymmetric notches was investigated by utilizing the giant magnetoresistance effect. The propagation direction of a DW was controlled by a pulsed local magnetic field, which nucleates the DW at one of the two ends of the wire. It was found that the depinning field of the DW from the notch depends on the propagation direction of the DW. (C) 2005 American Institute of Physics.
