Abstract: The magnetic field effect on the spectrum of excitons associated with various minibands in superlattices was studied by resonance Raman spectroscopy. It was found that the intensity of Raman scattering by acoustic phonons with the participation of the ground state of an exciton associated with the second miniband is sharply reduced even in weak magnetic fields if its velocity vector is orthogonal to the external magnetic field. This phenomenon was explained by the ionization of the exciton in the electric filed arising in the system of coordinate associated with the exciton moving perpendicular to the external magnetic field.
