Abstract
We study low-mobility 2D electron gas in GaAs quantum well in tilted magnetic field up to 45 T. Analyzing the behavior of the Shubnikov-de Haas (SdH) oscillations we obtain the value of g-factor, | g | = 0.9 ± 0.1 , which is noticeably larger than that predicted theoretically and obtained from optical experiments. Possible reasons of the discrepancy are discussed.
