The pattern formation in a magnetic wire forced by a time dependent magnetic field is studied. This system is described in the continuum limit by the Landau-Lifshitz-Gilbert equation. The spatio-temporal magnetization field exhibits two-soliton bound state solutions. Close to the parametric resonance instability, an amplitude equation allows us to understand and characterize these localized states.
