Abstract

We theoretically analyze resonant magneto-elastic interactions between standing perpendicular spin wave modes (exchange magnons) and longitudinal acoustic phonon modes in free-standing metal-ferromagnet multilayer structures. Whereas the ferromagnetic layer acts as a magnetic cavity, all metal layers control the acoustic frequencies and eigenmodes. Efficient resonant phonon-magnon interactions are governed by spectral and spatial mode overlap. Realistic simulations for gold-nickel multilayers show that sweeping the external magnetic field should allow for observing resonantly enhanced interactions between individual magnon and phonon modes.
