论文摘要
我们报告了杂化镁光子系统的电检测，该系统由磁性样品组成，该样品耦合到平面腔。虽然均匀的小猫模式在所有磁杆模式中具有最大的耦合强度，但它仅通过逆旋转式效果产生适度的电压信号。我们发现，通过引入更高的磁通模式，可以显着增强产生的电压，该模式具有更高的自旋泵送效率，并且通过Kittel模式几乎退化了。实验结果可以通过我们的理论模型来解释，并表明使用辅助磁杆模式可以实现具有强耦合和较大自旋电流的镁磷系统的构型。
We report on the electrical detection of a hybrid magnon-photon system, which is comprised of a magnetic sample coupled to a planar cavity. While the uniform Kittel mode has the largest coupling strength among all the magnon modes, it only generates a modest voltage signal by means of inverse spin-Hall effect. We have found that the generated voltage can be significantly enhanced by introducing a higher order magnon mode, which possesses a much higher spin pumping efficiency and furthermore, it is nearly degenerated with the Kittel mode. The experimental results can be explained by our theoretical model, and suggest that the use of an auxiliary magnon mode can realize the configuration of a magnon-photon system with both strong coupling and large spin current.
