A novel method for extending the frequency frontier in gravitational wave observations is proposed. It is shown that gravitational waves can excite a magnon. Thus, gravitational waves can be probed by a graviton–magnon detector which measures resonance fluorescence of magnons. Searching for gravitational waves with a wave length by using a ferromagnetic sample with a dimension l, the sensitivity of the graviton–magnon detector reaches spectral densities, around at 14 GHz and at 8.2 GHz, respectively.
