New article in Physical Review Applied

Our article "Harmonic and subharmonic magnon generation in a surface-acoustic-wave resonator" has just been published in Phys. Rev. Applied!

In this experimental work our colleagues at RIKEN and Kyoto University demonstrate for the first time phonon-to-magnon parametric down conversion in thin films. These nonlinear processes only occur after the system driving reaches a given threshold. The possibility of reaching the phonon-magnon instability threshold before the 3-magnon and 4-magnon thresholds is critical to observe this effect, and is enabled by acoustic drive and a sample designed to increase magnetoelastic coupling. This is a joint theory-experimental effort (and a joint publication with our previous work) with application in classical magnonics and the preparation of quantum magnonics states.
