## Abstract A global existence theorem is proved for the Landau–Lifshitz–Gilbert equations with biquadratic exchange coupling energy acting on the interfaces of a material composed by two ferromagnetic layers separated by a nonmagnetic one. This energy is not convex. The magnetization __M__ satisfi
