Abstract
We report on experiments of parametric frequency Conversion of a weak signal spin wave by a co-propagating strong pump spin wave. An effecti ve 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 sp ectrum of the film. A theoretical explanation of the observed phenomen on is given in terms of a four-wave parametric interaction process.
