Phase control of magnon-phonon coupling via magnetic field
Yasuhiro Todaka, Motoki Asano, Isamu Yasuda +3
We study the phase of the coupling between magnons and surface acoustic wave (SAW) phonons in magnetic thin films. The coupling constant changes from a real to a complex number as…
Nonreciprocal phonon propagation via spatially asymmetric magnon-phonon coupling
Hiroyuki Moriya, Motoki Asano, Daiki Hatanaka +3
Nonreciprocal propagation of surface acoustic waves (SAWs) based on the spatial asymmetry of magnon-phonon coupling is demonstrated. This nonreciprocity is enabled by an acoustic w…
Magnetoelastic Waves in Ferromagnetic Thin Films Mediated by Dipolar Interactions
Hiroki Yoshida, Ryohei Kono, Manato Fujimoto +4
Magnetoelastic coupling mediated by magnetic dipolar interactions is theoretically investigated in ferromagnetic thin films under an in-plane magnetic field. We develop a theoretic…
On-chip magnon polaron generation in mode-matched cavity magnomechanics
Daiki Hatanaka, Motoki Asano, Megumi Kurosu +3
Generation of magnon polarons, which are hybridized states resulting from strong magnon-phonon coupling, is a key to enabling coherent manipulation in acoustic and spintronic devic…
