After one year, this Early-Career Scientist Kakenhi stopped as the PI got a permanent position as CNRS researcher in France from December 2019. Within that year, the funded research was very fruitful as we demonstrated the first coupling between spin wave and exciton in a heterostructure constituted by an atomically-thin layer of MoSe2 and a thin YIG magnetic substrate. The optical absorption properties of MoSe2 are modulated by the spin waves at microwave frequency by magnetic proximity effects. Based on these results, a high impact paper is now in preparation, with a submission planned for this spring. This grant has launched a local and international collaboration with Iwasa group in Todai and A. Imamoglu in ETH Zurich.

一年后，这位早期职业科学家Kakenhi停止了研究，因为PI从2019年12月起在法国获得了CNRS研究员的永久职位。在那一年，资助的研究是非常富有成效的，因为我们证明了自旋波和激子之间的第一个耦合的异质结构构成的原子薄层的MoSe 2和薄YIG磁性基板。MoSe 2的光吸收特性在微波频率下通过磁邻近效应被自旋波调制。根据这些结果，目前正在编写一份影响力大的文件，计划于今年春天提交。这笔赠款已经启动了一个本地和国际合作与岩佐集团在东大和A。Imamoglu在ETH苏黎世。
