In the present work we study the pattern formation in a magnetic wire forced by a transversal uniform and oscillatory magnetic field. This system is described in the continuous framework by the Landau-Lifshitz-Gilbert equation. We find numerically that the spatio-temporal magnetization field exhibits a family of breather soliton states. We characterize different types of breathers as a function of the amplitude and frequency of the driven field.
