论文摘要
我们提出了一种在磁系统中非线性非逆转录转运的新机制。通过考虑双层三角形晶格上的非稳态磁有序，我们澄清说，局部标量性手性自由度是非重新转运的来源，它不需要任何相对论旋转的旋转轨道耦合，净标量，净标量，净标态和净磁化。我们根据模型参数依赖性在实际空间图片中的依赖性，显示了非对称条带调制与非旋转磁序下的非对称性传输之间的密切关系。
We propose a new mechanism of nonlinear nonreciprocal transport in magnetic systems. By considering a noncoplanar magnetic ordering on a bilayer triangular lattice, we clarify that a local scalar chirality degree of freedom is a source of nonreciprocal transport, which does not require any relativistic spin-orbit coupling, net scalar chirality, and net magnetization. We show a close relationship between the asymmetric band modulation and the nonreciprocal transport under the noncoplanar magnetic ordering based on the model-parameter dependences in the real-space picture.
