Abstract: 

Through numerical simulation by nonlinear Schrodinger equation magnetostatic wave soliton formation process is considered when amplitude and shape of initial pulse differ from soliton solution and non-soliton part can influence on soliton evolution. It is shown, that in lossless approximation soliton peak amplitude can oscillate with spatial period Λ: LD ≤ Λ ≤ 66 · LD (or friequency Ω: 0.015 · TD−1 ≤ Ω ≤ TD−1), LD и TD – length and time of dispersion. With dissipation corresponding to ferrite films, influence of non-solitin part leads to non-monotone behaviour of dependence peak output power versus power of input pulse.
