Localized precessional and nutational states in easy-axis iron and cobalt wires

Research output: Contribution to journalArticlepeer-review

Abstract

We report numerical stable and localized breather-soliton solutions of the Landau-Lifshitz-Gilbert equation for ferromagnetic wires of easy-axis anisotropy under the influence of an external periodic magnetic field and considering the detailed magnetocrystalline anisotropy field. Specifically, we study the existence and the precessional and nutational motion of these structures in iron wires (with cubic anisotropy) and in cobalt wires (with hexagonal anisotropy).
