Magnon has a potential to be a new information carrier because of its Joule-heating-less and long-distance propagation in ferromagnets. Recently, Das et al. demonstrated that magnon in Y3Fe5O12 is absorbed into an adjacent ferromagnet, Ni-Fe alloy (Py), and the absorption can be modulated by the magnetization direction of the Py. Although this study makes a progress toward a realization of magnonic device, a detailed principle of magnon absorption into metals has not been sufficiently clarified yet. Here, we study magnon propagation with several metallic middle strips, Py, Co, and Pt, to explore the mechanisms of magnon absorption into metals.
