Parametric frequency conversion with amplification of a weak spin wave in a ferrite film

IEEE Transactions on Magnetics, 1998
We report on experiments of parametric frequency conversion of a weak signal spin wave by a copropagating strong pump spin wave. An effective spin-wave frequency conversion with amplification occurred when the carrier frequencies of the co-propagating waves were in the spectral region of high negative dispersion in the dipole-exchange spin-wave ...

Relaxation of parametrically excited spin waves in ferrites at low temperatures

Soviet Journal of Low Temperature Physics, 1984
We have shown experimentally that the relaxation of a system of parametrically excited spin waves in ferrites is described by two characteristic frequencies, one describing amplitude damping of the spin waves, and the other describing their dephasing.

Magnonic noise in the parametric spin-wave pumping process

Japanese Journal of Applied Physics
Abstract This study investigates magnonic noise in the context of parametric spin-wave pumping in a yttrium iron garnet waveguide. By analyzing the input power dependence of parametric spin-wave spectra, we observed spectrum broadening and the emergence of additional pumping channels.
