The spatiotemporal structure formation problem is investigated in the region far above the transverse ferromagnetic resonance instability. The investigations are based on the dissipative Landau-Lifshitz equation and have been performed on a model which takes external fields, isotropic exchange fields, anisotropy fields and the demagnetizing part of the dipolar field into consideration. The numerical simulations for these models exhibit stationary domain structure in the rotating frame. Employing analytical methods and simplifying the model, certain features, such as the magnetization within the domains and the proportion of the system in each domain, are described analytically.
