Parametric Excitation and Instabilities of Spin Waves Driven by Surface Acoustic Waves

Advanced Physics Research
AbstractThe parametric excitation of spin waves by coherent surface acoustic waves in metallic magnetic thin film structures is demonstrated experimentally using Brillouin light scattering spectroscopy. Complementary micromagnetic simulations and analytical modeling reveal that, depending on the experimental conditions, the spin‐wave instabilities ...

Parametric generation of spin waves in nanoscaled magnonic conduits

Physical Review B, 2022
The research feld of magnonics proposes a low-energy wave-logic computation technology based on spin waves to complement the established CMOS technology and provide a basis for emerging unconventional computation architectures. However, magnetic damping is a limiting factor for all-magnonic logic circuits and multi-device networks, ultimately rendering

Nondegenerate Parametric Pumping of Spin Waves by Acoustic Waves

IEEE Magnetics Letters, 2017
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 ...

Sustained Amplification of Coherent Spin Waves by Parametric Pumping with Surface Acoustic Waves

npj Spintronics
Abstract Parametric amplification offers a route to overcoming intrinsic damping in spin-wave systems, a key challenge in the development of magnonic signal processing and computing technologies. Here we demonstrate the sustained amplification of coherent forward volume magnetostatic spin waves in a yttrium-iron-garnet thin film using a ...

Parametric resonance of spin waves in ferromagnetic nanowires tuned by spin Hall torque

Physical Review B, 2022
We present a joint experimental and theoretical study of parametric resonance of spin wave eigenmodes in Ni$_{80}$Fe$_{20}$/Pt bilayer nanowires. Using electrically detected magnetic resonance, we measure the spectrum of spin wave eigenmodes in transversely magnetized nanowires and study parametric excitation of these eigenmodes by a microwave magnetic

Parametric pumping of coherent spin waves by surface acoustic waves

Journal of Applied Physics
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
