The excitation, collision, and detection of soliton-like spin-wave pulses in ferromagnetic films are numerically simulated. The theoretical dependence of the pulse peak power at the output of the delay line on the peak power at the input of the input transducer is constructed for the first time. The experiment is compared with measurements. The shape of the nonlinear magnetization pulse excited and propagating in the film is theoretically studied as a function of the carrier frequency position relative to the backward volume spin-wave (BVSW) spectrum. The head-on collision of soliton-like BVSW pulses in ferromagnetic films is simulated for the first time. (C) 2002 MAIK "Nauka/Interperiodica".
