用Landau-Lifshitz-吉尔伯特自旋动力学方法研究了自旋电流间接控制反铁磁畴壁的位移。反铁磁畴壁可以通过扫描隧道显微镜的自旋极化隧道电流或通过交换耦合反铁磁-铁磁层系统中的电流驱动的铁磁畴壁来移位。反铁磁畴壁的间接控制为未来基于反铁磁材料的自旋器件应用开辟了一个新的和有前途的方向。
The indirect controlled displacement of an antiferromagnetic domain wall by a spin current is studied by Landau-Lifshitz-Gilbert spin dynamics. The antiferromagnetic domain wall can be shifted both by a spin-polarized tunnel current of a scanning tunneling microscope or by a current driven ferromagnetic domain wall in an exchange coupled antiferromagnetic-ferromagnetic layer system. The indirect control of antiferromagnetic domain walls opens up a new and promising direction for future spin device applications based on antiferromagnetic materials.
