We present a phenomenological theory for coupled spin-charge dynamics in magnetic van der Waals (vdW) heterostructures. The system studied consists of a layered antiferromagnet inserted into a capacitive vdW heterostructure. It has been recently demonstrated that charge doping in such layered antiferromagnets can modulate the strength, and even the sign, of exchange coupling between the layer magnetizations. This provides a mechanism for electrically generating magnetization dynamics. The central result we predict here is that the magnetization dynamics reciprocally results in inducing charge flows. Such dynamics makes magnetic van der Waals heterostructures interesting candidates for spintronics applications. To this end, we also show that these systems can be used to convert subterahertz-radiation-induced magnetization dynamics into electrical signals.

磁性范德华异质结构中的自旋电荷耦合动力学

我们提出了一种磁性范德华（vdW）异质结构中耦合自旋动力学的现象学理论。研究的系统由插入到电容式vdW异质结构中的分层反铁磁体组成。最近已经证明，在这种层状反铁磁体中的电荷掺杂可以调节层磁化之间的交换耦合的强度，甚至符号。这提供了用于产生磁化动力学的机制。我们在这里预测的主要结果是，磁化动力学会相互感应感应电荷流。这种动力学使范德华磁性异质结构成为自旋电子学应用的有趣候选对象。为此，
