摘要	It is shown that the resonant magnetic field B(C)* of a magnetopolaron bound to a Coulomb impurity in a GaAs/Ga(1-x)Al(x)As quantum well is lower than that of the "free" polaron owing to the effect of the Coulomb potential. Using the MacDonald method to treat the Coulomb potential, we come to the conclusion that B(C)* is related to the width of the quantum well, and that the resonant frequency is really below the frequency of LO phonons but is not "pinning" at a frequency near that of TO phonons.
