论文摘要
Weyl半法的磁纹理嵌入其拓扑结构中，并与其动态相互作用。在这里，我们检查了由自旋传输扭矩介导的域壁中电场诱导的结构相变，以及它们的占地面积。值得注意的是，域壁动力学导致瞬态，局部，非线性异常霍尔效应和非线性异常漂移电流，它是磁化动力学和域壁位置的直接探针。我们讨论了最先进的样本中的实验观察。
The magnetic textures of Weyl semimetals are embedded into their topological structure and interact dynamically with it. Here, we examine electric field-induced structural phase transitions in domain walls mediated by the spin transfer torque, and their footprint in charge transport. Remarkably, domain wall dynamics lead to a transient, local, non-linear anomalous Hall effect and non-linear anomalous drift current, which serve as direct probes of the magnetization dynamics and of the domain wall location. We discuss experimental observation in state-of-the-art samples.
