Abstract
AbstractHybrid dynamical systems have gained a huge momentum not only due to their exotic physical properties but also their compelling engineering standpoint, particularly owing to their potential for coherent information processing. Remarkably, magnon–magnon coupling is experimentally identified in Ni80Fe20 nanocross array with the number of spins reaching a very low value of ≈1012. Moreover, the coupling strength is effectively tuned via different external parameters, viz. microwave excitation power and the bias‐field orientation. Extensive simulations reveal that both the static and dynamical dipolar coupling contribute to the observed anticrossing phenomenon. Simultaneously, mode‐softening of spin wave tunable by subtle changes of bias‐field orientation is also observed. The findings can greatly enrich various hybrid phenomena with a magnonic platform.
