  Spatially homogeneous solutions of the Landau--Lifshitz--Gilbert equation are
analysed. The conservative as well as the dissipative case is considered
explicitly. For the linearly polarized driven Hamiltonian system we apply
canonical perturbation theory to uncover the main resonances as well as the
global phase space structure. In the case of circularly polarized driven
dissipative motion we present the complete bifurcation diagram including
bifurcations up to codimension three.
