论文摘要
我们观察到在微波泵送下沃克自旋模式的功率依赖性抗骨架，将铁磁铁放置在微波波指导中，该波导不支持任何离散的光子模式。我们将这种意想不到的抗粘体解释为泵诱导的磁化模式的产生，该模式强烈地伴随着Ferrimagnet的Walker模式。这种抗骨骼从泵中继承了出色的可调性，这使我们能够通过泵的功率，频率和波形来控制抗骨架。此外，就混合泵和探针频率的非线性相互作用而言，我们实现了这种抗骨骼的显着功能，即微波频率梳子。这样的频率梳子来自磁化动力学，因此不会遭受电荷噪声的影响。从其平衡中驱动的公开混合动力镁富集了抗肿瘤进行相干信息处理的利用。
We observe a power-dependent anticrossing of Walker spin-wave modes under microwave pumping when a ferrimagnet is placed in a microwave waveguide that does not support any discrete photon mode. We interpret this unexpected anticrossing as the generation of a pump-induced magnon mode that couples strongly to the Walker modes of the ferrimagnet. This anticrossing inherits an excellent tunability from the pump, which allows us to control the anticrossing via the pump power, frequency, and waveform. Further, we realize a remarkable functionality of this anticrossing, namely, a microwave frequency comb, in terms of the nonlinear interaction that mixes the pump and probe frequencies. Such a frequency comb originates from the magnetic dynamics and thereby does not suffer from the charge noise. The unveiled hybrid magnonics driven away from its equilibrium enriches the utilization of anticrossing for coherent information processing.
