▎ 摘　　要

A study of the magnetoexciton binding energy in graphene bilayers embedded in a dielectric is presented. The calculations are based on the relativistic Bethe-Salpeter equation assuming a strong magnetic field regime where the lowest Landau-level approximation takes place. It is shown that in graphene bilayer structures the magnetoexciton mass (binding energy) is four times lower (higher) than the corresponding magnetoexciton mass (binding energy) in coupled quantum wells with parabolic dispersion.
