摘要

We present a multiplexing device made of nanometric magnetic cluster chains and adsorbed clusters near the chains. We show that this nanosystem can transfer one magnon frequency from one chain to the other. With an appropriate choice of the geometrical or magnetic parameters of the structure, it is possible to control the desired magnon ejection. These results should have important consequences for designing integrated devices such as narrow-frequency microwave multiplexers.
