Theoretical investigations of phase transitions in magnetic multilayer structures are presented. We suppose that biquadratic and Heisenberg exchange energy between adjacent layers is of the same order of magnitude. Anisotropy energy is cubic. Our consideration is close to the Fe/Cr(0 0 1) superlattice. An investigation is given showing that two phases with noncollinear orientation of magnetization in adjacent layers can represent the ground state. In the case being considered external magnetic field aligned perpendicular to the layers direction induces a spin-reorientation transition. Other types of anisotropy are also discussed.
