Harmonic and Subharmonic Magnon Generation in a Surface Acoustic Wave Resonator
Yunyoung Hwang, Liyang Liao, Jorge Puebla +6
We experimentally observe the generation of magnon harmonics and subharmonics in an on-chip surface acoustic wave resonator incorporating a thin CoFeB film, us…
Classical and quantum theory of magnonic and magnetoelastic nonlinear dynamics in continuum geometries
Marco Brühlmann, Yunyoung Hwang, Jorge Puebla +1
We provide a theory of spin and acoustic wave coupled nonlinear dynamics in continuum systems. Combining the Landau-Lifshitz-Gilbert equations with the magnetoelastic Hamiltonian,…
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…
Valley-Selective Phonon-Magnon Scattering in Magnetoelastic Superlattices
Liyang Liao, Jorge Puebla, Kei Yamamoto +5
Phonons and magnons are engineered by periodic potential landscapes in phononic and magnonic crystals, and their combined studies may enable valley phonon transport tunable by the…
Acoustically driven magnon-phonon coupling in a layered antiferromagnet
Thomas P. Lyons, Jorge Puebla, Kei Yamamoto +5
Harnessing the causal relationships between mechanical and magnetic properties of van der Waals materials presents a wealth of untapped opportunity for scientific and technological…
Enhancement of acoustic spin pumping by acoustic distributed Bragg reflector cavity
Yunyoung Hwang, Jorge Puebla, Mingran Xu +3
Surface acoustic waves (SAWs) in the GHz frequency range can inject spin currents dynamically into adjacent nonmagnetic layers via spin pumping effect associated with ferromagnetic…
