Strongly Coupled Spin Waves and Surface Acoustic Waves at Room Temperature
Yunyoung Hwang, Jorge Puebla, Kouta Kondou +8
Here, we report the observation of strong coupling between magnons and surface acoustic wave (SAW) phonons in a thin CoFeB film constructed in an on-chip SAW resonator by analyzing…
