摘要：
当将亚铁磁体置于不支持任何离散光子模式的微波波导中时，我们观察到在微波泵浦下 Walker 自旋波模式出现了依赖于功率的反交叉。我们将这一意外的反交叉解释为泵浦诱导磁振子模式的产生，该模式与亚铁磁体的 Walker 模式发生强耦合。这种反交叉继承了泵浦的优异可调谐性，使我们能够通过泵浦功率、频率和波形来控制反交叉。此外，基于混合泵浦和探测频率的非线性相互作用，我们实现了该反交叉的一项显著功能，即微波频率梳。这种频率梳源于磁动力学，因此不受电荷噪声的影响。所揭示的远离平衡态的混合磁子学丰富了反交叉在相干信息处理中的应用。
英文摘要：
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.
