Nonlinear dynamics in magnonic Fabry-P' e rot resonators: Low-power neuron-like activation and transmission suppression
The study investigated nonlinear spin-wave dynamics in magnonic Fabry-Pérot resonators made of YIG and CoFeB nanostripes. They found that increasing excitation power causes a systematic downshift in spin-wave transmission gaps, leading to neuron-like activation and frequency-selective absorption. This demonstrates the potential for low-power, nonlinear elements in neuromorphic magnonic computing.
