Realizing strong magnon-phonon coupling (i.e., magnon-polaron formation) is challenging and typically involves a material or cavity that confines the magnon to a small volume. Here, by combining a YIG film with a ZnO acoustic resonator, Künstle and coauthors achieve magnetic field tuneable magnon-polarons in a virtually infinite magnetic film, and succeed in observing Rabi-like oscillations in the time domain.
