Abstract

We report that magnetostatic magnon transport can be controlled by local parametric excitation of short-wavelength magnons. We found that the parametrically excited magnon either enhances or suppresses the traveling magnetostatic magnons, depending on the frequency of the magnetostatic magnons. Our time-domain measurements of the magnon transport show that the change in the static magnetization due to the creation of the parametrically excited magnons is responsible for the control of the magnetostatic magnon transport. This result provides insight into magnon-based devices without complex microprocessing.
