Code and Data for "Quantum oscillations of valley current driven by microwave irradiation in transition-metal dichalcogenide/ferromagnet hybrids"

We theoretically study spin and valley transport in a TMDC/ferromagnet heterostructure under a perpendicular magnetic field. We find that microwave-driven spin pumping induces a valley-selective spin excitation, a direct consequence of the valley-asymmetric Landau levels in the TMDC conduction band. This process generates a pure valley current, which, as our central finding, exhibits pronounced quantum oscillations as a function of chemical potential. These oscillations provide a definitive experimental signature of the quantized valley states and establish a new pathway to interface spintronics and valleytronics.我们从理论上研究了垂直磁场下过渡金属硫族化合物（Transition Metal Dichalcogenides, TMDC）/铁磁体异质结中的自旋与谷输运现象。研究发现，微波驱动自旋泵浦会诱导谷选择性自旋激发，这是过渡金属硫族化合物导带中谷不对称朗道能级的直接结果。该过程会产生纯谷电流，我们的核心研究结果为：这类纯谷电流随化学势变化时会呈现显著的量子振荡。这些振荡为量子化谷态提供了明确的实验特征，同时为自旋电子学与谷电子学的交叉界面研究开辟了新路径。
