内容記述 | Spin waves hold promise for expanding the magnonics research field to include quantum information processing and classical information devices. Parametric pumping is considered a key technique to achieve this important advancement. Recently, a single-crystal iron has shown potential as a spin-wave excitation medium; however, parametric pumping in single-crystal iron films has not been investigated. In this study, we explored computationally and experimentally the characteristics of parametrically pumped spin waves in single-crystal iron thin films by respectively using large-scale micromagnetic simulations and a high-precision spectrum analyzer. The results demonstrate unconventional parametric pumping attributed to the competition between the anisotropic and excitation fields, emerging at external magnetic field and low power levels that would be insufficient to induce parametric pumping in isotropic materials. Systematic research on parametric pumping in iron could pave the way for low-energy spin-wave devices, enhancing quantum information device technology. | |||||||||||
