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 β B 2 to α B around 5 T as B increases, and both α and β become larger as the well-w
