Nondegenerate Parametric Pumping of Spin Waves by Acoustic Waves
The linear and nonlinear interactions between spin waves (magnons) and acoustic waves (phonons) in magnetostrictive materials provide an exciting opportunity for realizing novel microwave signal processing devices and spintronic circuits. Here, we demonstrate the parametric pumping of spin waves by acoustic waves in a ferrimagnet, the possibility of ...

Magnetoelastic parametric instabilities of localized spin waves induced by traveling elastic waves
A theory of parametric interaction between spin waves localized in a waveguide and traveling elastic waves is developed for ferromagnetic thin films. The presented theoretical formalism takes into account an arbitrary spatial distribution of the displacement field in the acoustic waves and an arbitrary magnetization in spin waves.

Parametric pumping of coherent spin waves by surface acoustic waves
This study investigates the parametric pumping of coherent forward volume spin waves using traveling surface acoustic waves in thin-film yttrium iron garnet. Theoretical analysis, micromagnetic modeling, and experimental validation of the nonlinear three-wave mixing interaction are presented. The energy and momentum imparted by the acoustic pump enable
