Abstract

Magnonic mode interconversion has paved the way for the integration of various developed magnonic functionalities, such as logic gates, switches, and multiplexers; however, it is limited by intrinsic magnetic damping. Therefore, this study proposes a potential amplification method to integrate spin-waves into magnonic circuits. The phase-matching conditions were tuned by introducing a feedback-ring structure. The results of microfocused Brillouin light scattering spectroscopy and micromagnetic simulations demonstrate the effectiveness of the spin-wave enhancement of feedback-ring structure. Consequently, spin-wave enhancement preserving phase information can be developed to realize integrated magnonic circuits.
