A micromagnetic study for the spin-reorientation transition in ultrathin magnetic films is reported. Phase diagrams of the magnetization configuration are presented. Scaling relations among the film thickness, exchange coupling, and magnetic anisotropies are revealed. Formulas are given for the energy stored in the film per unit area, which enable one to evaluate the surface anisotropy by ferromagnetic resonance techniques.
