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…

Acoustoelectric non-local spin wave power detector for studying magnon-phonon coupling
Hiroki Matsumoto, Yasuhiro Todaka, Takuya Kawada +2
We have developed a simple detection scheme to study spin waves excited by surface acoustic wave (SAW) in ferromagnetic thin films. Metallic antennas made of Ta and a ferromagnetic…

Magnon-phonon coupling of synthetic antiferromagnets in a surface acoustic wave cavity resonator
Hiroki Matsumoto, Isamu Yasuda, Motoki Asano +4
We use a surface acoustic wave (SAW) cavity resonator to study the coupling of acoustic magnons in a synthetic antiferromagnet (SAF) and the phonons carried by SAWs. The SAF is com…
