Abstract
The process of parametric amplification of the spin wave envelope solitons in ferromagnetic films with the use of parallel magnetic pumping was theoretically studied. Solutions obtained by numerical methods show that the value of the amplification coefficient depends on the relationship between the initial phases of the signal and the pumping carrier waves.
