Unconventional parametric spin-wave pumping in single-crystal iron films

This study explores a novel approach to exciting spin waves in single-crystal iron using parametric pumping. This technique achieves significant results at exceptionally low power levels, revealing unconventional behavior in this material. These findings suggest that single-crystal iron holds immense promise as a platform for spin-wave manipulation. A systematic investigation of parametric pumping in single-crystal iron paves the way for the development of low-power spin-wave devices.
