论文摘要
基于Yttrium和Calcium vanadium Iron石榴石（YIG和CVBIG）中的铁磁谐振器中的频率混合用于研究其非线性相互作用。铁磁性小猫模式是通过以接近共振的频率施加泵音的驱动的。我们探索两个非线性频率混合配置。在第一个中，探索了横泵音调和添加的纵向弱信号之间的混合，并将实验结果与Landau-Zener-Stuckelberg模型的预测进行了比较。在第二个中，通过在横向方向上混合泵和信号色调来使用交流测量，以研究稳定的螺旋和稳定节点吸引子之间的分叉。我们的结果适用于为射频和微波带的高增益开发敏感信号接收器。
Frequency mixing in ferrimagnetic resonators based on yttrium and calcium vanadium iron garnets (YIG and CVBIG) is employed for studying their nonlinear interactions. The ferrimagnetic Kittel mode is driven by applying a pump tone at a frequency close to resonance. We explore two nonlinear frequency mixing configurations. In the first one, mixing between a transverse pump tone and an added longitudinal weak signal is explored, and the experimental results are compared with the predictions of the Landau-Zener-Stuckelberg model. In the second one, intermodulation measurements are employed by mixing pump and signal tones both in the transverse direction for studying a bifurcation between a stable spiral and a stable node attractors. Our results are applicable for developing sensitive signal receivers with high gain for both the radio frequency and the microwave bands.
