Keywords:time-dependent Ginzburg-Landau, dipole-dipole interaction, magnetic thin material

We use the time-dependent Ginzburg-Landau (TDGL) equation with the dipole-dipole interaction. We investigated the two-dimensional spin system with the TDGL equation of motion. We developed a new method to predict the types of spatial patterns obtained after reaching the equilibrium states. We classified the types of patterns (phases) by a new approach, which is the key to our new fundings.
