| contents | The field of hybrid magnonics has gained significant momentum in recent years, driven by its potential to enable coherent information transfer and quantum transduction. This study delves into the tunable magnon-magnon coupling within a two-dimensional array of Ni80Fe20 (Permalloy) square nanomagnets by modulating its internal magnetic field configuration. Using a broadband ferromagnetic resonance (FMR) spectroscopy, we systematically investigate the influence of the orientation of external magnetic field and microwave power on the coupling properties. Our findings reveal a pronounced anticrossing behavior, indicative of robust magnon-magnon coupling, whose strength can be tuned through both static and dynamic external parameters. The ability to modulate coupling strengths in this system highlights its potential for developing flexible and adaptive magnonic devices, crucial for future applications in quantum information processing and spintronic technologies. This work not only broadens the understanding of magnon-magnon interactions in complex geometries but also opens new avenues for the design of next-generation quantum magnonic systems. |
