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

Characteristics of parametric spin waves in rectangular magnonic blocks
Journal of Physics D: Applied Physics, 2021 Abstract The characteristics of parametric spin-wave pumping are investigated in three rectangular permalloy blocks with in-plane aspect ratios of 12, 6, and 4. Micro-Brillouin light scattering (BLS) spectroscopy is utilized to detect the intrinsic properties of excited spin waves under various excitation conditions of an external ...

Parametric pumping of spin waves by acoustic waves
, 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, the possibility of which has long been ...

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 ...
