The magnetooptical anisotropy in strained quantum well structures is studied theoretically. As the source of this anisotropy the magnetic field induced mixing of light and heavy hole states is found. The anisotropy is also found in the frame of the multiple-band envelope-function approximation studying the influence of the barrier material on electronic states in the quantum well.
