The formation of solitons in ferrite films is modeled by a nonlinear Schroedinger equation, and numerical solution will indicate how multisoliton pulses form from a single pulse. Modeling is done using a narrow initial pulse of duration 13 ns with additional higher order terms in the equation. It is shown that the higher order terms will result in an asymmetric two-peak structure which is similar to experimentally observed soliton structures in yttrium iron garnet thin films.
