Magneto-photoluminescence (PL) experiments of very thin GaAs/Al 0.3 Ga 0.7 As quantum wells were performed in a magnetic field (B) of up to 20 T. It has been observed that the diamagnetic shift changes abruptly from Ξ² B 2 to Ξ± B around 5 T as B increases, and both Ξ± and Ξ² become larger as the well-w
