We report the first observation of magnetophonon resonances in the two-dimensional electronic system in single interface GaAs-AlₓGa_1-xAs heterojunctions and heterojunction superlattices. They result from inelastic scattering between Landau levels with resonant absorption of LO phonons of GaAs and yield a polaron mass mₚ*=(0.077±0.004)mₑ.
