论文摘要
在存在拓扑抗铁磁纹理的情况下，通过磁共振激发，我们证明了载体中的载体或防铁磁序的高阶谐波产生。这导致通过数量级增强载体动力学。有趣的是，生成过程以固有的方式发生，仅由非共线性抗抗铁磁序的S-D交换耦合与磁驱动的动态S-D交换参数之间的相互作用控制。因此，泵电流中高谐波的出现并不需要相对论的自旋轨道相互作用。因此，为了利用载体泵送中的高谐波发射的目的，将非连续性拓扑抗铁磁序列作为旋转轨道相互作用的替代方案。我们的提案在超级旋转旋转的高度活跃域中启动了对拓扑磁纹理开发的诱人观点。
We demonstrate the generation of high order harmonics in carrier pumping from precessing ferromagnetic or antiferromagnetic orders, excited via magnetic resonance, in the presence of topological antiferromagnetic textures. This results in an enhancement of the carrier dynamics by orders of magnitude. Interestingly, the generation process occurs in an intrinsic manner, and is solely governed by the interplay between the s-d exchange coupling underlying the noncollinear antiferromagnetic order and the dynamical s-d exchange parameter of the magnetic drive. Therefore, the relativistic spin-orbit interaction is not required for the emergence of high harmonics in the pumped currents. Accordingly, the noncollinear topological antiferromagnetic order is presented as an alternative to spin-orbit interaction for the purpose of harnessing high harmonic emission in carrier pumping. Our proposal initiates a tantalizing perspective for the exploitation of topological magnetic textures in the context of the highly active domain of ultrafast spintronics.
