Magnons offer a variety of attractive features for information processing: low dissipation, controllable non-linearity, short wavelengths at typical frequencies used in information technologies. Here, Metzger et al demonstrate control of a strongly coupled two-magnon-one-phonon state in antiferromagnetic CoF2.
