Spin pumping driven by bistable exchange spin waves is demonstrated in a Pt/Y 3Fe 5O 12 film under parametric excitation. In the Pt/Y 3Fe 5O 12 film, the spin pumping driven by parametric excitation selectively enhances the relaxation of short-wavelength exchange spin waves, indicating strong coupling between the exchange spin waves and spin currents at the interface through efficient spin transfer. The parametric spin pumping, furthermore, allows direct access to nonlinear spin wave dynamics in combination with the inverse spin Hall effect, revealing unconventional bistability of the exchange spin waves.
