Taming the photon-magnon interaction

In a study published in Physical Review Letters, researchers demonstrated control of the interactions between microwave photons and magnons, potentially leading to advances in quantum and electronic devices.

Scientific Achievement

The first demonstration of real-time control of the interaction between electromagnetic waves and spin excitations was achieved.

Significance and Impact

This work provides new opportunities for manipulating magnon-photon dynamics, opening a new direction for magnon-based coherent signal processing in both classical and quantum regimes.

Research Details

  • Enabled by novel device design, Floquet engineering was introduced into hybrid magnonic systems for the first time.
  • The frequency of magnons — quasiparticles representing collective spin excitations — was modulated at previously unachievable speeds, leading to new and controllable modal interactions.
  • The Center for Nanoscale Materials (CNM) magneto-electro-optical spectrometer was used.

Work was performed in part at CNM.
