摘要：

The pattern formation in a magnetic wire forced by a transversal uniform and oscillatory magnetic field is studied. 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 localized states that connect asymptotically a uniform oscillatory state with an extended wave. Close to parametrical resonance instability, an amended amplitude equation is derived, which allows us to understand and characterize these localized waves. Copyright (C) EPLA, 2012
