论文摘要
我们研究了磁性DW的理论上域壁（DW） - 元素 - 元素元素集体激发 - 在易于轴分层的van der waals（vdw）抗fiferromagnets中，它们作为耦合自旋超级流体的正常模式。我们发现，由于VDW磁铁中的自旋芯耦合，可以通过电压诱导的扭矩激活此类DW磁蛋白，从而为其低衰减和纳米级激发提供了一条路径。此外，可以通过应用对称性的静态磁场来控制频率下的电活激活和DW磁磁子的数量，从而增加了信号传输的可调性。我们的结果强调，VDW磁铁中的域壁为旋转旋转信息提供了一个有前途的平台，以进行旋转和磁性的广泛探索。
We study theoretically domain wall (DW) magnons-elementary collective excitations of magnetic DWs -- in easy-axis layered van der Waals (vdW) antiferromagnets, where they behave as normal modes of coupled spin superfluids. We uncover that, due to spin-charge coupling in vdW magnets, such DW magnons can be activated by voltage-induced torques, thereby providing a path for their low-dissipation and nanoscale excitation. Moreover, the electrical activation and the number of DW magnons at a frequency can be controlled by applying symmetry-breaking static magnetic field, adding tunability of signal transmission by them. Our results highlight that domain walls in vdW magnets provide a promising platform to route coherent spin information for a broad range of explorations in spintronics and magnetism.
