由于自旋转移力矩,磁畴壁可以被自旋极化电流移动。这开辟了在自旋电子存储器设备中使用它们的可能性,例如,在赛马场的仓库里自然地,在小型化的设备中,畴壁可以彼此非常接近并且影响彼此的动态。在这项工作中,两个分离的畴壁在不同的层,通过层间交换耦合相互作用已被认为是。其中一面墙是由自旋极化电流驱动的取决于如电流密度、层间耦合或钉扎电位的若干参数,两个畴壁的组合动力学可以非常强烈地改变,例如,墙壁的相关运动。此外,一个更微妙的效果出现作为抑制的步行者击穿伴随着增加的畴壁速度。
Magnetic domain walls can be moved by spin‐polarized currents due to spin‐transfer torques. This opens the possibility to use them in spintronic memory devices as, e.g., in racetrack storage. Naturally, in miniaturized devices domain walls can get very close to each other and affect each other's dynamics. In this work, two separated domain walls in different layers which interact via an interlayer exchange coupling have been considered. One of these walls is moved by a spin‐polarized current. Depending on several parameters as the current density, the interlayer coupling or the pinning potential, the combined dynamics of the two domain walls can change very strongly, allowing for, e.g., a correlated motion of the walls. In addition, a more subtle effect appears as a suppression of the Walker breakdown accompanied by an increase of the domain wall velocity.
