[16p-D419-7] Mode-tunable magnon-phonon interaction in a phononic crystal cavity magnomechanics
キーワード:フォノニック結晶、マグノン、強磁性共鳴
A phononic crystal cavity sustains multiple acoustic resonances with various vibrational strain distributions. In this presentation, we investigated the effect of the strain profiles on magnetoelastic effect governing interaction between ferromagnetic magnons and acoustic phonons. We found that longitudinal- and shear-strain dominant cavity resonances show different magnetic susceptibility to the magnetoelastic effect.
